Mirozhsky Monastery sits on the left bank of the Velikaya, a short walk south of the Krom across the river. It was founded in the 1130s, and the Cathedral of the Transfiguration at its heart contains the oldest and best-preserved frescoes in Russia — Byzantine-style murals covering virtually the entire interior surface, painted in the 1140s by Greek masters brought from Constantinople.
The paintings are extraordinary. The style is distinctly Byzantine — flat, golden, formally composed — but with a character that feels specifically Pskovian: earthy, intense, and completely unlike the more exuberant style of later Russian icon painting. The monastery also has a small museum of Pskovian art and a few other historic structures within its walls. Allow an hour and a half for a proper visit.
