The Vehkalahti Church (today known as the St. Mary's Church) was built in the 14th century at the place were the town of Hamina is now. The history of Vehkalahti churches begins in 1396, when the first mention of town was written to a letter by Vyborg castle lord.
The present stone church was built probably between 1430 and 1470. Because of it's location near the Russian border it was robbed and burned twice in wars during the 16th century. Church burnt also 1821 in fire of Hamina and got brand new outfit by the famous architect Carl Ludvig Engel.
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.
