It is a three-storey building that was erected during the Second Venetian domination and is probably modern with the Archaeological Museum. At that time it was a state building and housed the Governor's Office.
It is built of unfinished stone-masonry and its face is divided into three sections with horizontal zones. At the corners it is framed by a thick belt with vertical straight elbows. The elevation of the ground floor is achieved with its different proportions and especially with the large gap between its windows and the first zone. The reason for this is due to the need to raise the building on the narrow street, over the - not so bright - ground floor and not from aesthetic point of view.
The other two floors are crowned with a cylindrical belt. The building has been damaged by the addition of a balcony on the second floor, as it is perceived in the photo that there is a wooden balcony and only upstairs. This photo raises the question whether the building had only windows, which had the form of the Arsenal Museum (Archaeological Museum). Nowadays both balconies have cement corners.
Of course, the building is better known as the conch of Aga - Pasha, as it was used during the second Turkish rule. Later, after the revolution and during the period 1824-26, the offices of the Executive were operating here (according to some notarial documents).
In various written texts of foreign visitors it is stated that: "it was an old Turkish building near the walls (Ich-Kale), whose façade did not follow the usual pattern. On the ground floor there was a barn, the first floor of the barracks, and the government offices. " It also describes the steep wooden staircase of the building. This particular property was rated as the most suitable to accommodate Executive offices for many reasons.
First of all the most important role played by the building, as it is behind the parliamentary, ensuring direct communication through the old gate of the Mosque (on its southeastern side). This particular structure due to its large dimensions and interior layout could very well serve the needs of its use.
Finally, the access of three entrances served as access to each floor separately, ie access to the ground floor where the stables were located, is made from the main entrance to St. George Street, for the barracks the entrance is on the same street on the north-eastern side of the inner patio And for the offices there is a side entrance from the garden on the street of Constantinople.
The building is located in Konstantinoupoleos street (building block 192) has been restored and is in very good condition. The building is entirely used as a residence.
