The Vlah Church was built around 1450 on the site of Bogumils' necropolis, which had around 150 stećci (monumental, ornate tombstones). Only two of them are preserved today. Originally they faced each other, and were recently reoriented to be side by side.
The church was initially made of 'plot', i.e. of sticks, switches and mud. It was rebuilt three times, and finally in 1864 the church received its current form. A guard rail around the church was built in 1897 using barrels of Ottoman rifles captured in 1858 during the Battle of Grahovac.
References:The Pilgrimage Church of Wies (Wieskirche) is an oval rococo church, designed in the late 1740s by Dominikus Zimmermann. It is located in the foothills of the Alps in the municipality of Steingaden.
The sanctuary of Wies is a pilgrimage church extraordinarily well-preserved in the beautiful setting of an Alpine valley, and is a perfect masterpiece of Rococo art and creative genius, as well as an exceptional testimony to a civilization that has disappeared.
The hamlet of Wies, in 1738, is said to have been the setting of a miracle in which tears were seen on a simple wooden figure of Christ mounted on a column that was no longer venerated by the Premonstratensian monks of the Abbey. A wooden chapel constructed in the fields housed the miraculous statue for some time. However, pilgrims from Germany, Austria, Bohemia, and even Italy became so numerous that the Abbot of the Premonstratensians of Steingaden decided to construct a splendid sanctuary.
