Depart from the pier for a short drive to Tallinn's Old Town, where ancient walls and tower gateways can be seen. At Tall Herman Tower, walk the short distance up Toompea Hill to Palace Square. Visit the Alexander Nevsky Cathedral which dominates the city skyline, with numerous gold icons and mosaics inside. Continue along Tallinn's medieval cobbled streets and you'll see the Gothic Dome Church, also known as St. Mary's Cathedral. Proceed to the scenic viewpoint over the Lower Town rooftops, before rejoining your bus. Continue the tour to Kadriorg Palace, built in 1723 by Peter the Great in honor of his empress wife Catherine I. Its magnificent scale is enhanced by its setting on several levels, with upper and lower gardens in contrasting styles. The Swan Pond in the Lower Garden is a visual delight. Kadriorg means 'Catherine's valley' in Estonian, although the palace was seldom visited by the Tsarina. Since the Russian Revolution, the ornate palace rooms have been used as an art museum, and following closure in recent years, Kadriorg has reopened in its former glory. After viewing highlights of the European art on display, stroll through the Lower Garden back to your coach for the return to your ship. Note: Guests should wear comfortable walking shoes and be able to walk over uneven surfaces and cobblestone streets. Flash photography is not allowed in the churches and museum. An inside visit to the Dome Church is not possible on Sundays due to religious services. The Kadriorg Palace will be closed on Monday May 7th, 2012. This tour will only be available until July 1st, 2012, then closed for renovations.
