Three Architectural Icons.

The Peter and Paul Fortress, built by Peter the Great in 1703, is the oldest landmark in St. Petersburg. The needle-like spire of the cathedral rising from the bell tower of Peter and Paul reaches a height of 404 feet. Inside the cathedral are the extravagant tombs of almost all the Russian rulers since Peter the Great and a very ornate ceiling.

Smolny Convent of the Resurrection (Voskresensky) consists of a cathedral and a complex of buildings surrounding it, originally intended for a convent. It is considered to be one of the architectural masterpieces of the Italian architect Francesco Bartolomeo Rastrelli, who also redesigned the Winter Palace and created the Grand Catherine Palace in Pushkin, both of which we are due to visit.
The Singer building is a seven-storey building, built in modern style (1902-1904) for "Singer" manufacturing company.
