The Dark Garden, the city's main park, sits atop the Victoria and Pax Bastions, giving parts of it excellent views over the river. The park was established in the 19th Century, and one of its main features is an iron cross monument installed in 1853 - a memorial to Russian soldiers killed in the siege of Narva during the Great Northern War. The Dark Garden is also an excellent starting point for exploring Narva's medieval defense system. History buffs who want to learn more about the Old Town's bastions can pick up a detailed brochure called 'The Bastions Route' from the Tourist Information Centre, or visit http://bastion.narva.ee.
