The Kyiv Pechersk Lavra (Ukrainian: Києво-Печерська лавра, romanized: Kyievo-Pecherska Lavra), also known as the Kyiv Monastery of the Caves, is a historic lavra or large monastery of Eastern Christianity that gave its name to the Pecherskyi District where it is located in Kyiv. Since its foundation as a cave monastery during the 11th century, the Lavra has been a preeminent center of Eastern Christianity in Eastern Europe. Its printing house was an early part of the development of printing in Ukraine.
