St. Martin’s Cathedral (Katedrála sv. Martina) is one of Bratislava’s most important historic landmarks, located in the Old Town on Rudnayovo Square, directly below Bratislava Castle. This impressive Gothic cathedral dates back to the 14th and 15th centuries and is best known as the former coronation church of Hungarian kings and queens. A gilded replica of the Hungarian crown sits atop the cathedral tower, making it a defining feature of the city skyline. Inside, visitors will find a spacious three-nave interior, side chapels, and a blend of Gothic and Baroque architectural details reflecting centuries of religious history.

The cathedral is an indoor site and an active place of worship, and visitors are welcome during designated visiting hours. Entry to the main nave is generally free, while certain areas such as the crypt, treasury, or guided tours may require a small fee. Typical visiting hours are Monday to Saturday in the morning and afternoon, with more limited access on Sundays, though times may change depending on the season or religious services. Regular masses take place throughout the week, and sightseeing is paused during services.

Visitors should dress modestly and maintain a respectful, quiet atmosphere, especially when services are ongoing. Photography is usually allowed outside of mass times, often without flash. Due to its central location, St. Martin’s Cathedral is easy to combine with other Old Town attractions, and cafés and public transport are close by. Allow around 30–45 minutes for a visit, and consider checking local schedules on the day if you want access to specific areas or guided experiences.
