Tucked in the Rila Moun­tains, Rila Monastery is sim­ply stun­ning. It was ini­tial­ly found­ed in the 10th cen­tu­ry by St. John of Rila, a her­mit. Hun­dreds of pil­grims, and tourists come to the vis­it the site every year, and for cen­turies it has been a site of extreme spir­i­tu­al sig­nif­i­cance.
