The Osenovlashki Monastery, also known as Sedemte Prestola, is located in northern Bulgaria near the Balkan Mountains. According to legend, it was founded in the 11th century by seven boyars who settled with their families in the region. During Bulgaria's struggle for liberation, the monastery sheltered revolutionaries like Vassil Levski. Today, the functioning monastery has a central church surrounded by a stone wall, residential buildings, and a well-maintained garden. The church contains seven altars dedicated to Bulgarian saints, with wall paintings over 100 years old. The monastery is open for visitors to see its unique architecture and icons.
