Ovcha kupel (Bulgarian: Овча купел [ˌɔft͡ʃɐ ˈkupɛɫ]) is a district (rayon) of the Stolichna Municipality of Sofia City Province, Bulgaria.
[1] The name of the neighborhood is applied to the thermal water that comes out on the earth's surface: shepherds who led their flocks there knew that the sheep willingly walk in the swampy meadows.
On that place in 1933 was opened the Ovcha kupel Mineral Bath, built in 1925-1928 by architect Georgi Ovcharov [bg].
It is located starting at 6 km to the south-west of the city centre of Sofia, including the eastern part of the Lyulin Mountain.
The district includes some neighborhoods of Sofia – Ovcha kupel, Gorna banya, Suhodol, Karpuzitsa, and the village of Malo Buchino.
