The Hungarian Parliament Building in Budapest is a stunning example of Gothic Revival architecture and a must-see attraction. Guided tours are available in multiple languages and offer insights into the building's history and operation; solo exploration is not permitted inside. The building is generally accessible year-round, but opening hours may vary, and it's advisable to book tickets in advance, especially during peak tourist season. The cost of a tour is approximately €10-€20 depending on the tour type and discounts. A typical visit, including security checks and the guided tour, lasts about 1-2 hours. Consider allowing extra time to photograph the building from different angles along the Danube River.
