El Capitolio, Cuba's stunning former congressional building in Havana, offers visitors a glimpse into the nation's rich history and impressive architecture. It is generally accessible, though some areas may have stairs; guided tours often provide deeper insight and access to more sections, while solo visits allow independent exploration. There are no significant seasonal restrictions beyond standard operating hours, but checking for holiday closures is advisable. An entrance fee, typically around 10-15 USD, is usually required, and a visit generally lasts 1-2 hours, making it a perfect addition to a Havana itinerary. This iconic landmark, resembling the U.S. Capitol, is a must-see for its grandeur and central location.
