Dobbertin Abbey is a former Benedictine monastery of monks, afterwards housed a community of nuns, and later still a women's collegiate foundation. The abbey was founded during the Christianisation of Germany in about 1220 by Prince Heinrich Borwin II of Mecklenburg and was the first field monastery in Mecklenburg. The founder gave it to the Benedictines for a community of monks. 15 years later it was turned into a Benedictine nunnery.
In 1549 the Landtag at Sagsdorf Bridge near Sternberg resolved to introduce the Lutheran Reformation into Mecklenburg. Despite violent resistance the abbey was secularised and in 1572 converted into a Lutheran collegiate foundation for noblewomen.
In the middle of the 19th century the church was restored by Georg Adolf Demmler to plans by Karl Friedrich Schinkel. The work was completed in 1857.
In 1918 the abbey premises became the property of the state and were converted into a youth hostel. After World War II Soviet troops were stationed here, and destroyed much of historical interest.
From 1947 to 1991 the buildings were used as an old people's residential and care home. Then they were transferred to the responsibility of the charitable organisation of the German Evangelical Church, who set up a care home for the severely physically handicapped.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.
