Martonvásár Day Trip: Beethoven's Island Park, Half an Hour From Budapest

A White Castle, a Lake and a Lock of Beethoven’s Hair

Half an hour by train from Budapest, a white castle with stepped gables stands at the edge of a lake. Swamp cypresses stand by the water, an arched footbridge spans the lake beside an island, and around them spreads one of the few English landscape parks in Hungary that still keeps close to its original form. Beethoven knew the family who lived here. Inside one wing of the castle, a small museum keeps a lock of his hair.

Martonvásár is not a palace visit; most of the castle is a research institute. It is a park day with a story: the Brunszvik family, their friendship with Beethoven, a sister who opened Hungary’s first kindergarten, and a love letter whose addressee is still debated. This guide covers what you can and cannot see, which days work in winter, the tickets, the rules, where to eat, the trains, and how to add Lake Velence on the way home.

Which Day to Go

From 1 November the estate switches to winter hours, and the day of the week starts to matter.

Wednesday to Sunday works for everything. The Beethoven museum, the Agroverzum science center and the AGROBÁR café open 10:00 to 16:00, with last tickets at 15:15, and the park keeps the same hours. The operator says to allow at least two and a half hours to see it all, so arrive by 13:30 at the latest.

Monday and Tuesday work for a walk in the park only. The castle park is open every day in winter, 10:00 to 16:00, with last tickets at 15:15, but the museum, the science center and the café are closed. The Kindergarten Museum is closed on Mondays too.

Saturday is fine for the sights, but the direct train from Déli runs only once an hour. Start from Kelenföld instead (see Getting There). The two winter chamber concerts are also on Saturdays (see Concerts and Events).

The Castle Park and the Lake

The park is the reason to come. It has been a protected nature area since 1953. Paths lead past lawns and old trees to the main lake, where the view everyone photographs waits: the white castle across the water, the island and the arched footbridge. Give that view the most time.

The trees. Look for swamp cypresses by the lake, a dawn redwood, an American ironwood, plane trees, an Atlas cedar and an old small-leaved lime behind the castle. Teréz Brunszvik once had a circle of lime trees, her “lime-tree republic”, with each tree named after one of its members, and Beethoven was made a member. The operator says one small-leaved lime from that circle is still alive.

The island. The open-air Beethoven concerts have been held on the island every summer since 1958. In winter it is simply the center of the view.

In winter. The operator points to wintering tits, long-tailed tits and wrens in the trees, and gray herons and mallards around the lake. In early spring the ground is covered with winter aconite, snowdrops and wild garlic.

In 1815 the English traveler Richard Bright passed through and wrote that the park was so like England that he almost felt at home.

Brunszvik Castle: What You Can and Cannot See

The castle has changed shape several times. It began as a single-story Baroque house in 1784 and 1785, gained an upper floor in the Classicist style between 1822 and 1834, and took on today’s English neo-Gothic look in Géza Brunszvik’s remodel around 1875. Archduke Joseph bought it in 1893, and the Dreher brewing family in 1897. It served as a military hospital in the First World War, was rebuilt by the Drehers in 1923 to 1927 and was damaged in the Second World War. Since 1949 it has housed agricultural research.

That is why you cannot tour it. The estate belongs to the HUN-REN Centre for Agricultural Research, and most of the building is working institute space. Visitors can enter only the wing that holds the Beethoven Memorial Museum. There is no regular walk-in castle tour for individuals, and some areas of the grounds are marked as workplaces.

Next to the castle stands a baroque Catholic church designed by József Jung, built 1774 to 1777, part of the same group of buildings.

The Beethoven Memorial Museum

Hungary’s Beethoven museum opened in 1958 in the oldest part of the castle and was redesigned and enlarged in 2020 for the composer’s 250th birthday. It is small and interactive, and about 40 minutes is enough.

What you see.

• A lock of Beethoven’s hair in a medallion, the object the museum treasures most. Anton Sauter cut it at the composer’s deathbed, and it came to a choir in Pécs in 1870.
• An 1829 Streicher piano that belonged to the Brunszvik family. Liszt played it in 1846. It was restored in 2020 and is played about once a year.
• The former guest room, furnished in period style.
• A copy of Ferdinand Schimon’s portrait of Beethoven, made in 1879.
• Interactive music games that decode the musical messages Beethoven sent the family, and a VR tour of the castle rooms you cannot otherwise enter.

Up to 50 people can be in the exhibitions at a time. Personal photos are fine except in the marked areas of the museum.

Beethoven, the Brunszviks and the Immortal Beloved

The story starts in Vienna. In 1795 the countess Anna Seeberg subscribed to Beethoven’s Op. 1 piano trios, and in May 1799 she brought her daughters Teréz, then 24, and Josephine, 21, to the city. Beethoven gave them piano lessons for 16 days and wrote the song “Ich denke dein” (“I think of you”) in their album.

Their brother Franz Brunszvik became Beethoven’s friend and patron. The Appassionata sonata (Op. 57) and the Fantasia Op. 77 are both dedicated to him, and the F-sharp major sonata, Op. 78, to Teréz. The “Moonlight” sonata is dedicated to their cousin Giulietta Guicciardi, whose mother was a Brunszvik.

Did Beethoven come here? The exhibition takes on questions such as whether he really came to Martonvásár. In the museum’s account, his first contact with Martonvásár dates to his 1800 concert in Buda, and he finished the Appassionata here in August 1806.

The Immortal Beloved. After Beethoven died, an unaddressed, undated love letter to his “Immortal Beloved” was found. Drawing on about 30 years of research, the museum makes the case for Josephine: Beethoven wrote her 14 love letters after she was widowed in 1804, and they parted in late 1807 or early 1808. That is the museum’s view, and other candidates exist. The town calls itself the town of the Immortal Beloved all the same.

Teréz, meanwhile, made her own mark: in 1828 she opened Hungary’s first kindergarten, the Angyalkert (Angels’ Garden), in Buda. Her niece Blanka Teleki founded a girls’ school in 1846 and was later jailed for supporting the 1848 to 1849 revolution.

The Agroverzum Science Center

Every visit starts in the Agroverzum, the estate’s visitor center and the only way into the grounds. Its own exhibition covers agricultural science on two floors, with interactive displays and a science playground; allow about an hour. It is a good stop with children or on a cold day. The link to the place is real: Endre Pap bred MV5, the first hybrid maize in Europe, here, and it was certified in 1953.

In winter the science center keeps the museum’s hours, Wednesday to Sunday, 10:00 to 16:00. Its own ticket is 2,500 Ft, but it is better value inside the 4,500 Ft combined ticket.

Park Rules: Dogs, Bikes and Food

The estate is a nature area and a research site, and the rules are stricter than in a city park.

• No dogs. Pets are not allowed in the grounds.
• No riding inside. Bikes, scooters, roller skates and kick-bikes are not allowed in the park. Bike racks are in the Brunszvik-kert, and you push your bike from the gate to the racks.
• No fires, no smoking. Both are banned everywhere in the grounds, so leave the barbecue at home. The operator invites you to rest on the grass by the lake or on a bench.
• Café food stays at the café. Anything bought at the AGROBÁR is eaten at the bar or in the reception area.
• No swimming in the lake and no climbing the trees. No drones. Paid photo shoots such as weddings need a separate fee.
• Toilets and the cloakroom are in the Agroverzum and the museum, and you need a ticket to use them. Bags bigger than 30 by 30 cm go in the cloakroom when you visit the exhibitions.
• Step-free. The operator says all the buildings you can visit and the whole park are step-free.

Getting There

From Budapest by train. Direct trains run from both Déli and Kelenföld.

• Weekdays from Déli: the Z30 leaves every 30 minutes at :10 and :40 and takes 26 to 28 minutes, for 650 Ft (about $2) one way in second class. The first is at 05:10.
• Weekdays from Kelenföld: three trains an hour, the Z30 at :17 and :47 (19 to 21 minutes) and the G43 at :45 (25 minutes), for 600 Ft (about $1.80).
• Saturdays: the direct Z30 from Déli runs only hourly, at :10. Start from Kelenföld on the M4 metro instead: the Z30 at :17 and the G43 at :45 give you two trains an hour.

Coming back. Trains to Déli leave Martonvásár at :18 and, on weekdays, :48, and take about 31 minutes. The G43 at :44 runs to Kelenföld. After a winter visit, when the park closes at 16:00, walk back and take the 16:18 (Déli at 16:49), the 16:44 G43 to Kelenföld, or on weekdays the 16:48. In the evening trains leave at 20:18, 21:18 and 22:18, and the last useful train is the 23:18, arriving at Déli at 23:54 and Kelenföld at 23:45.

Train times and fares from the MÁV journey planner for Wednesday 4 and Saturday 7 November 2026, checked on 29 October 2026. The MÁV app shows the times for your day.

From the station. The main entrance is about 10 minutes on foot, roughly 850 m along the road beside the park. Everyone enters through the Agroverzum building.

By bus. Not worth it. The planner’s bus connections from Kelenföld take 1 hour 33 minutes to 2 hours 20 minutes with one or two changes, cost 930 to 1,120 Ft and run only about hourly. The train is quicker, cheaper and direct.

By car. Take the M7 motorway. The fenced visitor car park is entered from Kodály utca and is included in the ticket during opening hours. You cannot drive into the park without a permit. The car rental guide covers hiring one in Budapest.

For more on tickets and the network, see our guide to traveling Hungary by train.

A Day in Martonvásár, Hour by Hour

This plan is for a winter Wednesday to Sunday, when everything is open. It starts from Kelenföld, which works on Saturdays too.

• 9:45 G43 from Kelenföld, arriving in Martonvásár at 10:10. Walk to the Agroverzum, about 10 minutes.
• 10:20 Buy the museum ticket (3,500 Ft) or the combined ticket (4,500 Ft). Start with the Beethoven museum, about 40 minutes.
• 11:00 The park: the castle across the lake, the footbridge, the old trees. Allow at least an hour.
• 12:15 The Agroverzum exhibition if you bought the combined ticket, or coffee at the AGROBÁR.
• 13:15 Walk over to the Kindergarten Museum (900 Ft), if it fits the day.
• 14:18 Train back to Budapest, or stay for a late lunch at Postakocsi or Drago Rosso and take the 16:18.

Short on time? The park ticket and an hour by the lake make a fine morning on their own.

Combine It: Lake Velence

Martonvásár is about 15 km from Lake Velence, and the train covers the hop in 10 to 11 minutes for 450 Ft. On Saturdays there are two trains an hour, the G43 at :11 and the Z30 at :37. In winter the lake is a shoreline walk, not a swim. For a warm finish, our Velence Resort & Spa guide covers the spa on the lake.

If you like your day trips with a castle, the castles guide has the rest of the country, and Tata pairs a castle with a lake and, in late autumn, wild geese.

The Verdict

Martonvásár is one of the easiest castle-and-park days out from Budapest: a direct train, a 10-minute walk and a flat, quiet park where the castle sits across the lake like a picture. Do not expect state rooms; come for the view, the old trees and a small museum that tells the Beethoven and Brunszvik story well, and take the Immortal Beloved as the museum’s view, not the last word. In winter go Wednesday to Sunday if you want the museum too, arrive in the morning, and be at the gate before the 15:15 last tickets. On a Saturday, start from Kelenföld.
