The Stoa of Attalos is an ancient building located in the Agora of Athens, Greece. It was originally built by King Attalos II of Pergamon in the 2nd century BC as a gift to the city of Athens, and was used as a covered marketplace and meeting place. The Stoa of Attalos was a two-story building with a colonnade of 21 Doric columns on the ground floor and 21 Ionic columns on the upper floor. The building was about 115 meters long and 20 meters wide, and it had a central hall and several smaller rooms. During the Roman period, the Stoa of Attalos was damaged by fire and earthquakes, and it fell into disrepair. In the 1950s, the building was reconstructed by the American School of Classical Studies at Athens, using ancient building materials and techniques. Today, the Stoa of Attalos houses the Museum of the Ancient Agora, which contains exhibits on the history of the Agora and ancient Athens. The museum's collection includes pottery, coins, sculpture, and other artifacts from the ancient Greek and Roman periods.

The Temple of Hephaestus, also known as the Hephaisteion, is an ancient Greek temple located on the northwest side of the Ancient Agora of Athens. It was built in the 5th century BCE and is considered one of the best-preserved ancient Greek temples in the world. The temple was dedicated to the Greek god Hephaestus, who was the god of metalworking, blacksmiths, and craftsmen. The temple was also sometimes associated with Athena Ergane, the goddess of crafts. The Temple of Hephaestus is a Doric-style temple made of marble and limestone. It features 34 columns and a rectangular floor plan with a central cella (sanctuary) surrounded by a peristyle (a colonnade that surrounds the temple). The friezes on the temple depict scenes from Greek mythology, including the labors of Hercules and the battle between the Lapiths and the Centaurs. Despite being built over 2,400 years ago, the Temple of Hephaestus remains in excellent condition, thanks in part to its use as a Christian church in the Byzantine era. Today, it is a popular tourist attraction and an important example of ancient Greek architecture and engineering.
