In 1905, a complex was built in Ravineia Square ("Plasa") that housed a doctor's office as well as various shops, the rents of which covered the expenses of the "Bikur Cholim '' medical institution. In 1918 the building complex and the square were destroyed because of the new urban plan. In order to replace these constructions, the Israeli community built a complex of shops with an inner courtyard, on the corner of the (new) Komninon and Vasileos Irakleiou streets, dedicated to "Bikur Cholim''. A small synagogue named “Plaza” was built inside the courtyard, for the morning prayer of the workers in the market. Above the synagogue, another house was built through the donation of jeweler Samuel Bourlas. During the German Occupation, both synagogues were turned into a tavern.
