Little of the history of the old customs house, which is located on the coast road, is known to us. It is estimated that it was built around the middle of the 19th century by the architect Stamatios Kleanthis. He is best known for his urban plan of Athens, which he designed in cooperation with Eduard Schaubert, and his designs for various public buildings in the same city.

The façade of the Customs House is in three parts with an arcade supported on pillars, recalling the Venetian Arsenal in Syntagma Square, which seems to have been the inspiration. Generally the Customs House is simple in design, rectangular, with symmetrical entrances and windows. It creates a sense of balance and harmony, in keeping with the neo-classical movement.
