St. Bridget's Church was erected in 1396 in the Gothic style on the site of the former small chapel, which in 1374 housed a corpse of St. Bridget, who was being transported from Rome to Sweden. The church was burnt to the ground during WWII and  reconstructed in 1973. In 1992 St. Bridget's Church was granted title of Lesser Basilica by pope John Paul II. The church is best known as a sanctuary and shelter for the leaders of the Solidarity Movement under martial law. The austere church interior is adorned with a unique work of art, a monumental amber altar, which is arranged in the form of a triptych with an icon of the Working Class Madonna in the centre.
