The town of Uglich dates from the 10th century.  In the 16th century, Ivan the Terrible used Uglich as a base for attacks against the Tartars. After Ivan's death, his son Dmitry moved there with his mother.  Seven years later he was murdered, probably on order of Boris Gudunov. The town revolted, which led to its own massacre. This was the beginning of what is called the Time of Troubles. The Church of St. Demetrius-on-the-Blood, shown above, is named in honor of these events.
