First record of the St. Peter's Church dates back to 1209. The church was a masonry construction and therefore undamaged by a city fire in Riga that year. The history of the church can be divided into three distinct periods: two associated with Gothic and Romanesque building styles, the third with the early Baroque period. The middle section of the church was built during the 13th century, which encompasses the first period. The only remnants of this period are located in the outer nave walls and on the inside of a few pillars in the nave, around which larger pillars were later built.
The second period dates to 15th century, when master builders Johannes Rumeschottel from Rostock supervised the construction of the sanctuary, based on the St. Mary's Church in Rostock. The old bell tower was replaced in 1456, and a bell was hung in the new tower in 1477. A 136 metres (446 ft) octagonal steeple was added to the tower in 1491, which, along with the church's front facade, dominated the silhouette of Riga. The tower collapsed 11 March 1666, destroying a neighboring building and burying eight people in the rubble.
Three identical portals by Bindenshu and Andreas Peterman were added in 1692. The third period of construction dates to 1671–90. The newly renovated church served for a mere 29 years, for lightning struck and set fire to the tower and church 10 May 1721. Only the church and tower walls remained standing after the fire. Reconstruction of the church began immediately under the direction of the master carpenter Tom Bochum and master mason Kristofer Meinert. By 1723 the building already had a temporary roof. Johann Heinrich Wilbern took over supervision of the project in 1740, and under his direction a new 69.6 metres steeple was built in 1746.
The church burned down 29 June 1941. Conservation and restoration began 1954 with research by architect Pēteris Saulītis. The work was carried out from 1967 to 1983 under the direction of Saulītis and architect Gunārs Zirnis. The St. Peter's Latvian Lutheran congregation resumed services in the church 1991, and the church was returned to the ownership of the Evangelical Lutheran Church of Latvia on 4 April 2006.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.
