Museum St. Isaac’s Cathedral
St. Isaac’s Cathedral ranks among the world’s tallest dome structures. It is St. Petersburg’s largest Orthodox cathedral, which is now a museum. Among other things, St. Isaac’s offers an impressive display of semiprecious stones that cover its indoor surfaces, dozens of mosaics, and over 350 outdoor sculptures.
The colonnade of St. Isaac’s is definitely a place worth visiting. Being the city’s most famous observation deck, it gives its visitors an opportunity to enjoy the view of the Neva and St. Petersburg’s historical areas.
