Sergiyev Posad is the religious center of the
Moscow Region as its first monastery was founded in 1337. The monastery began as a church built by Sergius of Radonezh, made out of wood, and by 1345 was recognized as a place of religious worship. Town status was granted to Sergiyev Posad in 1742. In the 16th and 17th centuries, the religious center continued expanding into new monastery buildings, living areas, and stone walls, which withheld a
Polish siege from 1608 to 1610. In the 18th century, wooden monasteries were mostly destroyed and began reconstruction and settlement (roads, hotels, stable, and hospice). Lavra was closed in 1919 after the
Russian Revolution, like all other places of worship in the
Soviet Union. The town's name, alluding to St. Sergius, has strong religious connotations. Soviet authorities changed it first to just
Sergiyev in 1919 and then to
Zagorsk in 1930 in memory of the revolutionary
Vladimir Zagorsky. Compare: {{cite book Sergiyev Posad was invaded by Germany in 1941 but reopened later that year during the
Second World War, and continued to serve as a religious and historical center of Russia. The original name was restored in 1991. ==Administrative and municipal status==
