Over the large arch of the nymphaeum, there is a pediment with a relief of a distinctively feminine symbolism depicting the deities Eros, Artemis and Dionysus.
Among them are a Roman bridge and a rock-hewn theatre, with nine tiers of seats and an orchestra nineteen meters in diameter, also a nymphaeum, an aqueduct, and a large prostyle temple with portico and colonnades.
As an archaeologist, Dobruský personally headed the excavations of the Zlatna Panega asclepieion in 1903–1906, the Ognyanovo nymphaeum in 1904 and the ancient cities of Oescus (1904–1905) and Nicopolis ad Istrum (1906–1909).
