About Haus des Meeres

Haus des Meeres is an aquarium and terrarium built inside a WWII flak tower in Mariahilf. The tower itself is a stark concrete anti-aircraft fortress from 1944, and the contrast between the brutalist exterior and the tropical fish inside is surreal. The shark tank, the tropical house (with free-flying birds and crocodiles), and the monkey section are the highlights. But the real reason to visit is the rooftop: 360-degree panoramic views of Vienna from a platform on top of the tower, with a cafe and bar. EUR 11 adults, EUR 6 children. The tower exterior still has original WWII-era murals and a climbing wall.

Good to know

Tips, answered

EUR 11 adults, EUR 6 children. The aquarium is fine but not world-class. The real reason to go is the rooftop: 360-degree Vienna views from the top of a WWII flak tower, with a cafe. The exterior still has original wartime murals. The tropical house with free-flying birds is a hit with kids. Takes about 1.5-2 hours. The building itself is the most interesting part.

Plan for about 2 hours.

Haus des Meeres is in the Mariahilf neighborhood of Vienna. The address is Fritz-Grünbaum-Platz 1, 1060 Wien, Austria. The area is well-served by metro.

This works well at any time of day, though mornings tend to be quieter. Weekdays are less crowded than weekends.

Landmark

Schonbrunn Palace

Schonbrunn Palace stands as Vienna's answer to Versailles, serving as the summer residence of the Habsburg dynasty and claiming the title of Austria's most visited attraction. This UNESCO World Heritage site offers multiple ways to explore its imperial splendor. The Grand Tour costs EUR 24 and takes you through 40 opulent rooms over 50 minutes with an excellent audio guide. You'll walk through Rococo state rooms, the Great Gallery where European powers danced during the famous Congress of Vienna, Maria Theresa's private chambers, and the very room where six-year-old Mozart performed for Empress Maria Theresa in 1762. The Imperial Tour (EUR 20, 22 rooms) covers the highlights if you're short on time. The palace opens daily at 8:00 AM, closing between 4:30 PM and 6:30 PM depending on the season. Booking online will help you skip entrance queues, especially during summer months and weekends when crowds can be overwhelming. The gardens alone justify the visit, and they're free to explore. These vast baroque gardens stretch endlessly, featuring the dramatic Neptune Fountain, the romantic Roman Ruin folly, and the challenging maze (EUR 6 extra). The crown jewel is the Gloriette pavilion perched on the hill, offering panoramic views of both palace and city. The walk up is free, though the cafe terrace costs EUR 4.50. Don't miss the Tiergarten Schonbrunn (EUR 24 adults, EUR 18 children), the world's oldest zoo dating to 1752. Despite its age, it's thoroughly modern and excellent, housing giant pandas and maintaining impressive conservation programs. Allow at least half a day for the palace, gardens, and one additional attraction. Wear comfortable walking shoes and bring water, especially in the summer.

Park & Garden

Schonbrunn Zoo (Tiergarten)

Schonbrunn Zoo is the oldest zoo in the world (1752) and genuinely one of the best. Founded as the imperial menagerie by Emperor Franz I, it has evolved into a modern conservation-focused zoo with naturalistic enclosures that do not feel depressing. The giant pandas are the star attraction (one of the few European zoos with giant pandas). The rainforest house, the aquarium, and the big cat enclosures are highlights. The zoo sits in the grounds of Schonbrunn Palace, so you can combine the two. EUR 24 adults, EUR 18 children 6-18, free under 6. Allow 3-5 hours.

Park & Garden

Esterházypark

Esterházypark sprawls across what used to be the palace gardens of one of Austria's most powerful noble families, the Esterházys. You'll find yourself in a genuine neighborhood park where Viennese families actually spend their weekends, complete with two excellent playgrounds, a basketball court, and table tennis tables that locals use constantly. The mature chestnut and plane trees create natural shade pockets perfect for picnicking, while the open lawns give kids room to run wild. The park feels refreshingly unpretentious compared to Vienna's more formal gardens. Parents chat on benches while toddlers navigate the modern playground equipment, teenagers shoot hoops, and dog walkers follow the winding paths between flower beds. You'll hear more German than English here, which gives you a real slice of local Vienna life. The atmosphere stays relaxed even on sunny weekends when the place fills up with families. Most guidebooks skip this place entirely, which works in your favor. The park's biggest strength is also its limitation: it's purely functional rather than scenic. Don't come expecting Instagram moments or historical significance beyond the Esterházy connection. The playground equipment is top quality, but if you don't have kids, you'll probably exhaust the park's appeal in 30 minutes rather than the suggested hour.

Shopping

Mariahilfer Straße

Mariahilfer Straße stretches 1.8 kilometers from MuseumsQuartier to Westbahnhof station, making it Vienna's longest shopping strip. The pedestrianized middle section between Neubaugasse and Museumsquartier creates a car-free zone where you'll find everything from H&M and Zara to Austrian chains like Humanic shoes and Peek & Cloppenburg. The western end near Neubaugasse shifts into indie territory with vintage stores, record shops, and quirky boutiques that locals actually use. The pedestrian zone feels spacious compared to cramped European shopping streets, with wide sidewalks and outdoor café seating spilling onto the pavement. You'll weave between street musicians, families with strollers, and teenagers treating the area like their outdoor mall. The atmosphere changes as you move west: corporate retail gives way to handwritten window signs and experimental fashion stores. Weekend afternoons bring the biggest crowds, especially around the major department stores like Gerngross. Most guides treat this as one homogeneous shopping street, but that's wrong. The eastern half near MuseumsQuartier is standard international retail, fine for basics but nothing special. The real finds are west of Neubaugasse where rent gets cheaper and creativity increases. Skip the overcrowded Saturdays and go on weekday evenings when stores stay open until 8pm but foot traffic drops significantly. Budget around 15-25 EUR for vintage pieces, 40-80 EUR for local designer items.

Market

Weihnachtsmarkt Schloss Schönbrunn

Schönbrunn's Christmas market transforms the palace's front courtyard into Austria's most elegant holiday shopping experience, with 70+ wooden chalets selling everything from hand-carved nativity scenes to Swarovski crystal ornaments. You'll find quality crafts here that outshine other markets: wooden toys from the Tyrol region (€15-45), hand-painted ceramics from local artisans (€8-25), and delicate glass baubles that somehow survive the flight home. The imperial yellow facade is a fitting backdrop, especially when lit up after dark. The market flows in a neat grid pattern around a central Christmas tree, making it easy to navigate without the chaos of Vienna's bigger markets. Food stalls cluster near the palace entrance, serving proper Wiener schnitzel sandwiches (€8) alongside roasted chestnuts and mulled wine (€4-6). The whole place has a refined atmosphere where you can browse without getting elbowed by tour groups. Classical musicians often perform near the fountain, adding to the palace ambiance. Most guides rave about this market, but honesty is the best policy – the craft quality varies wildly between stalls. Skip the generic souvenir booths near the main entrance and head straight to the back rows where local artisans set up shop. The food is overpriced compared to neighborhood spots, but the Kaiserschmarrn (€9) is genuinely excellent. Come on weekday mornings when vendors are eager to chat and demonstrate their crafts.
