Suplacu de Barcău

Suplacu de Barcău (Berettyószéplak, Siplak) is a commune in Bihor County, Crișana, Romania with a population of 4,356. It is composed of six villages: Borumlaca (Baromlak), Dolea (Dólyapuszta), Foglaș (Fogás; Fogaš), Suplacu de Barcău, Valea Cerului (Cserpatak) and Vâlcelele (Blágarét).

History
The two oldest villages in the commune, Suplacu de Barcău and Borumlaca, were partly depopulated between 1686 and 1692, as a result of the Great Turkish War; the previous inhabitants began to return once hostilities ceased. Numerous families of Slovak colonists arrived in the late 18th century, leading to the appearance of two other villages, Vâlcelele and Valea Cerului. The final two, Dolea and Foglaș, date to 1905 and 1916, respectively.
