St Petersburg

An enchanting city with a rich and fascinating history, St Petersburg is the Jewel in Russia’s Imperial Crown. It was from here that the aristocrat tsars ruled over Russia for two centuries until the Russian Revolution in 1917. Today remnants of the city’s grandiose past can be seen in its beautiful historic centre. Made up of a series of canals this UNESCO World Heritage site is dotted with elegant baroque bridges, impressive rococo architecture and spectacular palaces. Visit the fabulous Winter Palace - once home of the tsars, where you will find the world famous Hermitage collection. Explore Peter and Paul Fortress - the oldest building in the city, with its impressive baroque interior. Take a look around St Isaac’s Cathedral – one of the world’s largest cathedrals and the beautiful Church on Spilled Blood, which was built on the spot where Tsar Alexander II was murdered in 1881. You can also pay a visit to the spectacular Summer Gardens at palatial Peterhof, which overlooks the Gulf of Finland and Catherine Palace at Tsarkoe Selo.

Pskov & Pechory

Located in the north west of Russia, just 30km from Estonia, the ancient and historical city of Pskov, with its fortified riverside Kremlin and Trinity Cathedral, is a firm favorite amongst tourists. Pskov dates back as far as 903, making it as old as the country itself. Pskov has retained much of its medieval outer-town walls and is crammed full of tiny, picturesque churches with fabulous examples of Byzantine architecture. Within the Kremlin's crumbling walls is the gorgeous Trinity Cathedral, which is definitely a highlight of any visit to Pskov. A short drive from from the city brings you to the beautiful little settlement of Pechory, famed for its monastery where you can explore the peaceful grounds of this still-working cloister which is home to over 70 monks. The monastery was founded in 1473 when the first hermits settled in local caves. If monastic law permits, enter the spooky burial caves where over 10,000 monks bodies lie in coffins, piled on top of each other in the tunnel walls.
