The Hungarian Parliament Building, an outstanding example of neo-Gothic architecture, is located on the banks of the Danube River in Budapest. It's best to visit this landmark either solo or as part of a guided tour, which offers insightful access to its magnificent interior, including the Dome Hall where the Holy Crown of Hungary is showcased. Guided tours are available in multiple languages, costing around €8-20, and you should allocate 45 minutes to an hour for the visit. It's recommended to book tickets in advance to secure your spot, especially during peak tourist seasons like spring and summer. The Parliament is easily accessible by public transport, with nearby metro stations and trams. It is closed on certain national holidays, so check the schedule accordingly. For stunning views, try visiting around sunset when the building is beautifully lit.
