Archaeological excavations in the interior and the closest surroundings of St. Michael's church revealed evidence of several phases of its building modifications. The first building phase is represented by a single nave church with an apsis, altered several times in the following medieval period, with radical Baroque transformation and subsequent adaptations resulting into current state of the church. The latest survey of the evolution of the western tribune of the Romanesque sanctuary is presented in detail, including its place in a wider context of sacred architecture of medieval Bohemia. Also the anthropogenic stratigraphy in the main nave is characterised, including the evidence of the local stonemason's guild activity in the high medieval ages.
