Groznjan is a small town on the top of a terraced hill in Croatia. It was established by Romans as a fort kastel due to its high vantage point. As even the town’s inside terrain is very leveled, the initial Roman plan had to adjust to local topography, sacrificing the usually strict grid pattern. Groznjan often changed its rulers and inhabitants, yet it is uniform in style: its medieval urban complex built by Venetians in the 13th century remained largely untouched, and as the town is so small, each renovation took on the scope of the whole city. Recently, the town started attracting more residents due to its contemporary jazz educational programs, and new houses and public spaces grew outside the original kastel walls in an organic pattern along the roads leading up to Groznjan.
