Tsar Peter I (reigned 1682-1725) established his own headquarters in Preobrazhenskoye, and was a regular guest in the German Quarter. He neglected his father's palaces, instead concentrating on the military (Preobrazhensky Lifeguard regiment, established 1687) and supporting the industries spreading on both banks of the river. Bartolomeo Rastrelli erected "Annenhof", a summer residence for empress Anna of Russia, in Lefortovo in 1731. Annenhof burnt down in 1746 and was eventually replaced by Catherine's Palace (), designed by Giacomo Quarenghi; the palace now houses a military academy, and the former palace gardens have become a public park. Elizabeth of Russia built her country palace in Rubtsovo, on the site of Mikhail's former residence (), from 1735 to 1743.
