In the vicinity of the village, many early Byzantine religious ruins can be found, and the village may be described as an open-air museum. Especially the ruins of a 5th- or 6th-century church (now called Emirzeli) is an important example of Byzantine architecture.

Animal husbandry, which once constituted the major economic sector of the village, is on the decline. The main agricultural crops are tomato, cucumber, olive and some fruits. Although the village hosts valuable archeological sites, at the moment, tourism plays no part in the village's economy.
