The Rossgarten Gate is one of seven surviving city gates of Kaliningrad. Named after the district Rossgarten, the current gate replaced a previous version of the gate from the beginning of the 17th century. It was constructed between 1852-1855 under the supervision of Wilhelm Ludwig Stürmer. The gate was damaged after the war, but restored afterwards and currently houses a café-restaurant called Solnetsnyy Kamen ('Solar Stone').
The gate consists of only one passage of about four meters wide. On both sides of the passage three casemates are located, so the gate in total has seven openings. On top of the facade of the gate can be found a series of merlons, divided into two parts by the central elevated part of the gate. The gate itself has two high octagonal turrets. Above the main arch of the gate a lookout area is situated, again equipped with merlons. Reliefs of the Prussian generals Gerhard von Scharnhorst and August Neidhardt von Gneisenau decorate the main arch. While the city side of the gate is a highly decorated, the outer side does not have any decorative ornaments.
References:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
