The post-Franciscan Church of the Assumption of the Blessed Virgin Mary, erected in the second half of the 14th century, is one of the most outstanding artistic and architectural achievements of sacral architecture in Poland. In the 14th century it was the highest hall church in Central Europe with the naves and aisles 26.8 metre high. The church provided inspiration for the extension of St. Johns’ Church in Toruń and St. Mary’s Church in Gdańsk in the 15th century. According to the Franciscan rule, the church does not have a tower but three rather small ave-bell towers instead. The church and the cloister remained in Franciscan hands up to the Reformation period, i.e. up to 1559. The cloister, which was the oldest and most significant in the whole of the Teutonic state, was the residence of the Prussian custos. Here during the synod of 1243 a papal bull was announced dividing the Teutonic state into four dioceses.References:
Sirmione castle was built near the end of the 12th century as part of a defensive network surrounding Verona. The castle was maintained and extended first as part of the Veronese protection against their rivals in Milan and later under the control of the Venetian inland empire. The massive fortress is totally surrounded by water and has an inner porch which houses a Roman and Medieval lapidary. From the drawbridge, a staircase leads to the walkways above the walls, providing a marvellous view of the harbour that once sheltered the Scaliger fleet. The doors were fitted with a variety of locking systems, including a drawbridge for horses, carriages and pedestrians, a metal grate and, more recently, double hinged doors. Venice conquered Sirmione in 1405, immediately adopting provisions to render the fortress even more secure, fortifying its outer walls and widening the harbour.
Thanks to its strategical geographical location as a border outpost, Sirmione became a crucial defence and control garrison for the ruling nobles, retaining this function until the 16th century, when its role was taken up by Peschiera del Garda.
