The Varnavin Monastery
After Barnabas's death, monks came from various lands to settle at Red Hill, followed by farmers, and population spread along the river toward the Volga. The monks established a cenobitic community known as the Varnavinsk wilderness-monastery.
At the site they built two churches: one in honor of the Most Holy Trinity, and a second dedicated to Saint Nicholas the Wonderworker raised over the saint's grave. The town of Varnavin eventually developed around the monastery.
