The complex of buildings at the spa of Kallithea has been designed by the well known Italian architect Pietro Lombardi and was constructed in 1929, under the commands of the Italian administrator of the Dodecanese. The building was inaugurated on the 1 st of July 1929 during a grandiose ceremony, after there had been accomplished the repair and the construction of the road leading from the town of Rhodes to Kallithea. During the next year, 1930, it was added the upper atrium, and the open area around the building reached its final form.

Today the complex of the buildings is comprised of three different parts:

a. the round square with a nice fountain, in front of the main entrance.

b. a semi-circular atrium for the distribution of water

c. the complex of the sanitary establishment

All three parts of the construction are connected with and surrounded by gardens and small parks, with stone paved walking paths and resting places, forming an excellent environment in harmony with the natural landscape.

Everywhere it is evident that the architect intended to combine elements of all cultures that were developed on the island during its long history. Thus, we can find features coming from the Doric antiquity, from the Roman period, from Byzantine times, from the period of the Knights of Western Europe, from the Arabs and the Ottomans, alongside with the local folk style.

Today the complex, out of use, has been abandoned, but it is planned the restoration and renovation of the place, in order to become suitable for various uses.
