Sightseing in St Petetersburg
Winter is a magical time in St Petersburg and Keith advises starting at the breathtaking Hermitage, in the Winter Palace. "But tailor your trip wisely," he adds. "There are 350 exhibition rooms and some three million items in the collection of this incredible museum. St Isaac's Cathedral is majestic, the Church of the Saviour on the Blood epic and try, also, to catch some Russian Orthodox choral music – the Sunday morning recital at the Preobrazhenskiy Church is deeply atmospheric."
