Originally a frontier outpost, after the annexation of Thessaly in 1881 it was turned to other uses, including as a public school.
Disused since the 1960s, the building had fallen into ruin, but after its repurposing as a museum was decided, it was completely restored in the 1990s.
From 1997, the 7th Ephorate of Byzantine Antiquities began work on establishing the museum, initially in the ground floor, which was completed in 2004.
[1] The museum operates under the auspices of the 24th Ephorate of Byzantine Antiquities and features exhibits from across the region of Phthiotis, ranging from Early Christian times to the Ottoman period.
The middle room hosts an exhibit of the region's numismatic history, as well as the private collection of Konstantinos Kotsilis, with coins ranging from Ancient Greece to Sassanid Persia and modern times.
