Kastoria is filled with old manors dating to the Ottoman period, while parts of the old Byzantine walls also stand.
Stone bridges are an important part of the traditional architecture of Kastoria. The best known is the bridge of Zouzouli, the bridge of Koromilia, the Koutsoumpli bridge and the bridge in Beriki.
The Bridge of Zouzouli, located in a remote area on the southern tip of the prefecture of Kastoria, is built over the waters of the stream of Zouzouli and connects mt. Smolikas with mt. Voios. It is arched, has a length of 25 meters and a height of 7 meters. Constructed in 1880 by artisans coming from Konitsa. The construction was financed from either a man, in memory of his brother who drowned in the river, or from a ruler who, moved by the drowning of a little girl, wanted to build the bridge.
The bridge of Koutsoumpli is located between the mountains of Voio and Smolikas, over the river of Zouzouli and it previously connected the villages of Eptachori and Zouzouli. Its arch is 14 meters wide, 8 meters high and it has a total length of 33 meters and a width of 2.40 meters.
The bridge in Beriki has a very thin arch and a great height. It was manufactured by master builder Sdrolios, who came from the village of Ntempeni (now Dendrochori), probably in 1866. Next to the bridge there was possibly a watermill and an inn. Probably, this is where the name of the region came from (inn Beriki).
The bridge of Koromilia is built over the Ladopotamos river and it used to connected the village of Koromilia with the one of Dendrochori. It is arched and has a length of 26 meters, a width of 2.80 meters, a height of 7 meters and an arch opening of 16 meters. It was built in 1865 and consists of limestone and schist slate.
