The fortress in the centre of Taavetti is part of the chain of fortresses built during the period of Russian rule in the late 18th century to protect St. Petersburg. The village of Marttila, at the intersection of four roads, was considered a strategically important place to fortify. Here, the Ylinen Viipurintie road leading from Vyborg to Hämeenlinna and the road leading inland from Hamina intersected. You can explore the fortress on your own, either by following the signposts, touring the frisbee golf course, or even having a picnic.
