First reference to Vranov as a boundary guard stronghold can be found in Kosmas Chronicle as early as around 1100. In 1687 a Vienna architect Jan Bernard Fischer from Erlach began with a baroque reconstruction. The Hall of Ancestors became the dominating feature of the castle at that time. It has an oval ground plan and was decorated by frescoes with antique motifs (Jan Michael Rottmayr) and by statues of owners of that time – the Althan family (Tobiáš Kracker). Next phase of reconstruction after 1723 was carried out by a Vienna master builder Antonín Erhard Martinelli.  It was when the eastern entrance wing and the double staircase with statues from mythology were built (Lorenzo Mattielli). In the 80s of 18th century the southern and western wings were completed and this way today’s ground plan of castle courtyard was created. By the end of 18th century castle interiors were all furnished in the classicism style. Beside preserved furniture Vranov pottery can be seen in several rooms as well. It was produced in a local manufacture between 1799 - 1882.
