The nymphaeum or sanctuary of the Three Graces (or Kharites or three nymphs) is located near the southwestwern corner of the village of Ognjanovo (previously called Marica, and before that Saladinovo). It was explored already in 1886 by Vaclav Dobruski, and again in 1984–1988 during the repair of the nearby dyke. Excavations yielded numerous dedications to the Graces and to Zeus and Hera. The remains date from the Hellenistic and Roman periods. A text from the site indicates that the sanctuary was associated with the town of Bourdapa.
