Munichia or Munychia (/mjuːˈnɪkiə/; Greek: Μουνιχία or Μουνυχία) is the ancient Greek name for a steep hill (86 metres (282 ft) high) in Piraeus, Greece, known today as Kastella (Καστέλλα). This is a fashionable neighborhood in central Piraeus. On the top of the hill is a Greek Orthodox church named after the Prophet Elijah. The narrow streets around the church are surrounded by picturesque houses. The Veakeio Theater, known for its summer performances is located here.
