Bridge of Katsogiannis near Spilaio

Approximately 2 kilometres east of Spilaio stands the Bridge of Katsogiannis, also known as the Bridge of Spilaio or the Mill Bridge. It crosses the Velonia River, a tributary of the Venetikos, and takes its name from Katsogiannis, the miller who worked at the nearby mill of the Church of Saint Athanasios. Constructed around 1800, the bridge was originally three-arched, with a total length exceeding 50 metres and a width of 2.60 metres. The central arch rises to an approximate height of 7 metres. Today, it unfortunately does not survive intact: the southern part has been replaced with reinforced concrete, while the two northern stone arches remain — still sufficient to reveal its significance and former beauty.
