St Mary's Basilica, the Bazylika Mariacka, is the great landmark of Gdańsk. Its square brick tower dominates every view of the Main Town, and the church is so large that it is usually counted among the biggest brick churches anywhere. It was built over more than a century and a half in the late Middle Ages, when Gdańsk was one of the richest trading cities on the Baltic, and its scale is a statement of that wealth. Step inside and the effect is the opposite of the heavy exterior: a vast, bright, whitewashed hall of slender pillars and star-shaped vaults. Look for the astronomical clock, an intricate medieval timepiece, the carved altars and memorials of merchant families, and the chapels that line the walls. In season you can also climb the tower to a viewing platform over the rooftops, the river and the shipyard cranes. The basilica stands one street north of the Long Market, a minute or two from the Royal Route.
Visiting hours: the basilica is open to visitors from Monday to Saturday from 11:30 to 18:00, and on Sundays and holidays from 14:00 to 18:00. Tourists can visit when Mass is not being celebrated, and half of the church, including the presbytery and the main altar, is open to visitors; the front section is reserved for prayer. A modest donation is asked at the visitor desk, with reduced rates for children, students and seniors.
The tower: from November to April the tower is closed, so a winter visit is to the church only. From May to October the tower opens from Tuesday to Sunday, with groups of up to fifteen climbing every half hour. Tickets are sold only at the visitor desk on the day, not in advance, so arrive early in summer. The climb is long and steep, with several hundred steps, and is not suitable for anyone with mobility or heart problems.
Who it suits: everyone. First-timers should step inside even briefly, as the scale of the interior is one of the great sights of the Baltic. Couples will enjoy the quiet late in the afternoon, and families can make a game of finding the astronomical clock. Dress respectfully, keep your voice down and avoid wandering during services.
