3 must-see hop-off attractionsWhen it comes to picking the three must-see hop-off destinations in St Petersburg, there are three obvious candidates. The first place you need to hop off is the Hermitage Museum, which houses the second largest art collection in the world. The collection began with the purchase of 225 paintings from a Berlin merchant and today contains more than three million pieces! The buildings housing the collection are almost as spectacular as the collection itself. Another place you can’t miss is the Peter and Paul Fortress. The city’s original citadel, the fort was founded by Peter the Great at the same time as the city itself. Today, it’s home to the State Museum of Political History of Russia, which provides a fascinating insight into the turbulent political story of Russia over the last century. The final place you definitely have to visit is St Isaac’s Cathedral. This incredible building is a true architectural treasure and the spectacular panoramic views from its colonnade are the very best in St Petersburg.
