The original condition of the Karlin apartment, which is located on the top floor of the immovable cultural monument from 1837 and is the work of architect Jan Ripota, did not show any historical elements before the reconstruction and at first glance it looked like an ordinary apartment unit in an ordinary apartment building. This was because the craftsmanship values had been hidden by the previous building alterations. The architect Petr Jančálek, however, decided to restore them after their discovery.
