The town was founded in the 10th century, which is all well and good. But I am far more likely to remember that this was the site of the murder of Dmitrii, son of Ivan the Terrible, in 1591.
The tales of Ivan really are quite colorful, and a great many of the bloody events of his reign are commemorated in stone. In this case by the Church of St. Demetrius.
*The Palace of Tsarevich Dmitrii, also visible from the steamer landing, is a bit of a tourist trap. All reproductions and recreations.
