Steiner Tor is a-preserved gate, originally built in the late 15th century but refashioned in the Baroque style in the city of Krems an der Donau, in the Wachau valley. It is considered the symbol of the city. Until the last third of the 19th century, the city of Krems was surrounded by a wall. This was systematically razed, and three gates were also removed. From 2005, celebrating the 700-year anniversary of the city rights, the Steiner Tor was restored as much to its original as possible.
Outside the portal are towers flanking both sides, which, like the lower floor of the gate, date from the late Middle Ages. On the right of the archway is a small stone coat of arms mentioning Emperor Friedrich III, and the year 1480 in Roman numerals. This is believed to date the restoration of the fortifications that had become necessary because of the destruction wrought by Hungarian troops in 1477. The tower building dates from much more recently, and dates to the Baroque period during the reign of Maria Theresa, 1756. Outside the gate, the Steiner Tor was originally threatened by flooding from the Danube. On the inner side of the stone door is a mounted memorial which commemorates such a disaster in 1573.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.
