Fontanka River
Until the mid-18th century the Fontanka River marked the southern boundary of Saint Petersburg. Along its banks stood the spacious messuages of members of the Russian Imperial Family and of the nobility, the most brilliant being the Summer Palace and the Anichkov Palace. In 1780–1789 Andrey Kvasov superintended the construction of the granite embankments and approaches to the river. The river-bed was regularised as well.
