The Corner House (Stūra māja) in Vecrīga, Riga, Latvia, is a profound historical museum that served as the former KGB headquarters, offering crucial insight into Latvia's Soviet occupation. It's easily accessible in the city center, though visitors with mobility needs should confirm specific access for all exhibition areas. Both self-guided exploration of the permanent exhibition (1-2 hours) and pre-booked guided tours (2-3 hours, highly recommended for deeper context) are available. The museum generally operates year-round, with seasonal variations in opening hours. Expect an approximate entrance fee of 5-15 EUR, with additional costs for guided tours. This is a somber and educational experience, not a light-hearted attraction, and visitors should be prepared for challenging historical content.
