The Abbasian historical complex is situated in one of the old districts of Kashan, named “Sultan Amir Ahmad”. This complex has been constructed from the year 1830 to the year 1835 by the Kashani businessman, late Seyed Ibrahim, and is of paramount importance in regard to its architecture and decorations.

This complex covers an area of almost 5,000 square meters and its foundation stands at nearly 7000 square meters. Note that this complex is a five-storey building.

The Abbasian historical complex maintains five courtyards; each of which has a unique architecture. Following the demise of the first owner; this complex was turned into five separate houses. In the year 1995, this complex was purchased and renovated by the Board of Trustees for Renovation of Kashah’s Historical Fiber, with the financial assistance of the Ministry of Industries and Mines. This complex was registered as a national monument in the year 1998.

The Abbasian Historical Complex maintains a rich design, while its plasterworks, paintings, and Islamic architecture decorations are highly beautiful and delicate, such that this complex was nominated for the receipt of the prize for the best Iranian-Islamic residential building.

In the past, due to usage of subterranean water ducts, homes were constructed below the surface of the street. The other reason behind such architecture is the insulating nature of soil against heat and cold. In fact, homes which maintained such architecture were cool in summer and warm in winter. Meanwhile, this historical building and complex consists of summer and winter quarters and in each season particulate parts of the complex had been used with due regard to climatic conditions.
