The large greenhouse was intended for the cultivation and storage of tubers of flowers, which were planted flower beds in the palace parks in the springtime and prepared Peterhof for the summer. Over time, the greenhouse was expanded and rebuilt, and the fountain, standing in the garden, has not changed. It depicts a newt - the son of Poseidon defeats the sea monster allegory of Peter the Great's victories over the Swedes. Translated with Google Translate
