The Herakleidon Museum is a non-profit cultural organization founded in 2004 by Paul and Anna-Belinda Firos. It consists of two buildings in the district of Thissio, next to the Acropolis, the Ancient Agora and the Temple of Hephaestus. The first building is located at 16 Herakleidon street, and the second one is 150 meters further, at 37 Ap. Pavlou street in Athens.During the first decade of its operation, the museum focused on artistic activities and organized exhibitions with artworks of renowned artists such as M.C. Escher, Victor Vasarely, Carol Wax, Constantin Xenakis, Adolf Luther, Francesco Scavullo, Toulouse-Lautrec, Edgar Degas, Edvard Munch, Sol LeWitt and others. At the same time, a plethora of cultural activities allowed visitors to explore the essence of each artist's perspective. Today, the Herakleidon Museum has evolved into an interactive center of science popularization and a technological museum that focuses on antiquity, with emphasis on the achievements of the ancient Greeks. Based on the philosophy of the educational programs that Greece itself established, such as the triptych of Science, Art and Mathematics, the museum continues to offer original educational programs, inspired by its exhibition "EUREKA, Science, Art and Technology of the Ancient Greeks."

The Etz Haim Synagogue is located in the Thiseio area of Athens, at Melidoni Street 8, across from its largest and youngest Sephardic synagogue, Beth Shalom. It was built in 1904 by Greek Romaniote Jews who came from Ioannina, and for this reason it is also called the "Romanian" or "Yannonian" synagogue by the oldest members of the community. The first Jewish Community of Athens in the modern era was formally established in 1889 and before the first congregation was built, informal galleys were operating, such as the house of the Yusurum family at the junction of Ermou and Karaiskakis streets, while another is testified that it was operating on Ivy Street. The synagogue suffered serious damage from the 1999 earthquake, mainly on the roof, which was radically renovated in 2006 and officially opened on 30 June 2007 by the Jewish Community of Athens. However, due to renovation, architectural interventions took place inside it and this created objections. The Etz Chaim Synagogue only works during the great religious celebrations of the Jewish Community, and on the regular basis for all religious ceremonies is the central synagogue of Athens, Synagogue Beth Shalom. Both synagogues are managed by Rabbi Gabriel Negrin, who was elected by the council of Athens’ Jewish community following the death of the longtime leader Jacob Arar in 2014.
