Following the partitions of Poland, in the 19th century, Łazienki fell into the hands of the Russian tsars. In the period from 1819 to 1830, at the request of the new owners architect Jakub Kubicki rebuilt the Belvedere in the late-classicist style and subsequently erected new pavilions in the gardens – the Egyptian Temple and Temple of Diana. He converted the former Trou Madame pavilion into a new guardhouse and a school, hence today it is best known as "Podchorążówka" (Cadets’ Hall).
