St. Mary's Church (Bazylika Mariacka) in Gdańsk's Śródmieście district is a monumental Gothic brick basilica, renowned as one of the largest in the world, offering a rich historical and architectural experience. The main nave is generally accessible for visitors, though climbing the tower, a highlight for panoramic city views, involves numerous stairs and may not be suitable for those with mobility issues. Both solo exploration and guided tours (often with audio guides available) are excellent options to appreciate its intricate details, including the famous astronomical clock. The church is open year-round, but seasonal variations may affect opening hours and tower access, particularly during inclement weather. While entry for prayer is usually free, a modest fee is typically charged for tourist access to designated areas or for ascending the tower. A visit, including the tower climb, typically lasts between 1 to 2 hours. Visitors are reminded that it is an active place of worship, so respect for ongoing services is appreciated.
