Pella Palace (Пеллинский дворец) was a summer residence built during the reign of Catherine II of Russia for her grandson, future emperor Alexander. It was situated on the left bank of the Neva River, 30 km east of Saint Petersburg, where the town of Otradnoye now stands. If completed, it would have been Russia's largest imperial palace. Pella, partially built in 1785-1789, has been razed to the ground by Catherine's son, Paul of Russia. Not only the buildings disappeared, but very few images of it survived the Battle of the Palaces: existing knowledge of Pella relies on a few facade elevations and watercolors by Giacomo Quarenghi and an elaborate drawing on Catherine's fan, also based on Quarenghi's drafts.
Extremely fond of her grandson Alexander, the Empress liked to think about him as the new Alexander the Great. In November 1784 she purchased the estate of Pallila (also called Ivanovskaya Myza) from the heirs of Ivan Neplyuev. Ivanovskaya has already been a well-appointed estate with two-storey wooden manor, four guest houses and various services. The park contained a pool, connected with Neva with a canal, and was modestly adorned with statues and follies. Catherine stayed in the manor occasionally before major construction commenced.
In 1785 Ivanovskaya was renamed to Pella, an allusion to the birthplace of Alexander the Great and the illustrious future intended for Alexander. In April 1785 Catherine wrote to Melchior Grimm that she planned to set up an English landscape park around Pella; in fact, earlier, on March 13, 1785, she authorized Ivan Starov's draft for a spacious, proper imperial palace. Groundbreaking ceremony was celebrated on July 17, 1785 when work has already been underway.
