The Historical and Architectural Complex “Simbirskaya Zasechnaya Cherta” appeared in Ulyanovsk around the remnants of defensive works, stretching in the middle of the XVII century from the western borders of the Moscow State to the Urals - the defense line. Fragments of these fortifications were found only in 2000 at the site in front of a dwelling house.
The Complex "Simbirskaya Zasechnaya Cherta" contains a fragment of an earth rampart and a reconstructed watchtower, as well as an exposition "Mills of Simbirsk" with an active mock-up of a water mill. The first two tiers of the tower house a permanent exhibition dedicated to the Russian army of the 17th century. Besides the original uniform and weapons of the military of those days, here you can see models of guns, shields and drawings by Erich Palmquist, the Swedish military attaché in Russia at that time. The third tier contains an exposition that introduces Russian wooden serf architecture and the construction of fortifications.
