The monastery is located in the Athens district of Kolonaki, south of Lycabetus hill, not far from the center of Athens. This is the only active monastery located in the central part of the city. The terrain here, however, is quite quiet. The monastery itself is small, cozy, all overgrown with greenery. It originated in the XVII century and is named after the name of its first superior, Petraki. Later on, the monastery was ruled by several other hegumen from the Petraki dynasty. The main (and only) temple of the monastery, dedicated to the Archangels Gabriel and Michael, was built long before its foundation, in the XIII-XIV centuries. This is a three-nave basilica with characteristic for its time architecture. The preserved paintings of the cathedral date back to the 18th century. The territory of the monastery has a rectangular shape, the main entrance is from the west. One-two-storey cell buildings are located along the southern and northern borders. Currently, the monastery is thriving and enjoys great prestige of the Orthodox Church of Greece.
