Tsarskoye Selo
A new park which later became Alexander Park was established in the 1770s to the west of the Catherine Palace, and in 1792–1795 Giacomo Quarenghi built the Alexander Palace at the north-eastern border of the park for the future emperor Alexander I. In 1808, Alexander I merged the Tsarskoye Selo with Sofia and proclaimed it a town and the seat of Tsarskoselsky Uyezd. In 1808, he appointed William Heste as the town architect, which post he held until his death in 1832. Heste compiled a master plan for Tsarskoye Selo, with division into quarters and associated gardens and orchards. Most residents moved from Sofia to Tsarskoye Selo and the former was converted to a residence of a military regiment. By 1817, Tsarskoye Selo had 15 streets, 354 buildings and a population of 4,000.
