It was built in 1730, during the second period of Ottoman rule in the town, and it briefly functioned as the first parliament building of the Provisional Administration of Greece, hence its common name.

[2][3] Given the absence of written sources and the multiple changes of use that have significantly altered the original design of the building, the exact date of construction of the mosque remains a mystery.

[4] The walls of the old mosque were plastered and whitewashed, while the covering of the domes and the openings were also renovated, as well as the interior, in particular the raised wooden floor which was traditionally reserved for women.

[3] Finally, on July 2, 1827, during some clashes that took place between the revolutionaries, a mortar hit the building, resulting in the death of the deputy Christos Gerothanasis who was inside at the moment.

[4] The masonry consists of isodomic cut limestone, potentially coming from the monastery of Karakala located about ten kilometers northeast of Nafplio.

[8] Inside the prayer hall, the mihrab with polychrome painted decoration was discovered in 1990 and highlighted during the mosque's restoration campaigns between 1994 and 1999.

[8] In the lower part on the ground floor, the mosque consists of ten small rectangular rooms resulting from the rearrangements during the transformation into a prison.

[8] A common passage with the neighboring madrasa constituted a secondary entrance for merchants and led to the base of the minaret located at the south-west corner, of which only a few traces remain today.
