Bologa (Latin: Resculum; Hungarian: Sebesvár) is a village in the Cluj county, Transylvania, Romania.
The village is situated at the confluence of the Crişul Repede and Henţ (Sebeş or Săcuieu) rivers (the confluence is known as "gura apelor" - "the mouth of the waters" - in the local toponymy) and at the foot of the Vlădeasa mountains (1863 m), part of the Apuseni Carpathians. The closest town is Huedin.
Transportation links: on the European route E60. Small railway stop ("haltă") for regional trains ("Personal") on the Oradea-Cluj-Napoca main Romanian railroad. On the national road 128 which heads South towards Săcuieu.
The ruins of the castrum are still visible today in the place still called "Grădişte" which means "fortified settlement", although most of the area is cultivated. The ruins of a Roman bath also exist near the castrum.
The Hungarian king, Sigismund of Luxembourg after signing in Braşov an alliance treaty against the Turks in 1399 gave the fortresses of Bran and Bologa to Wallachia's prince Mircea cel Bătrân.
Built to watch the strategic road that went from Oradea inside Transylvania, the fortress also served as a refuge for the local population throughout the centuries. It gained in importance when the Turks conquered Oradea in the 17th century as it was hindering the tax collection. The sultan ordered its demolition but the order was not carried out. The fortress was later destroyed by the Austrian soldiers through explosion. The tower and many walls are still standing. In the mid 20th century the tower lost its roof, probably the last wooden element of the ruins. All that remains is stone.
The Second Vienna Diktat in 1940 temporarily re-situated Bologa in Hungary, right at the border (some teritorry on the hills nearby remained in Romania). This began yet another period of tensions between ethnic Romanians and Hungarians which ended in 1945 with the restoration of the Romanian Western border.
A stone quarry was opened in 1930 providing dacite stone for the Budapest-Bucharest road. The quarry was later on taken over by the Romanian railways, most of whose embankments are made of stone from the area. After 1989 the quarry was privatised and did not do very well comparing to neighbouring quarries, so it stopped being the main source of income for the villagers. The upcoming highway projects in Romania are expected to improve the quarry prospects.
Forestry is also active in the area, though more active in the neighbouring valley of Drăgan.
Agriculture is widely practiced but the land size and quality in the hilly-montainous area only allows for the individual needs of the land owners.
The majority of inhabitants have the surname Potra, which according to accounts is a link to the colonists from Patras (the Potras/Patras variation exists in other Greek-related names too). Most of the Potras are said to have been shepherds, which probably allowed them not to become serfs to the dominant Hungarian nobility, thereby maintaining their relative prosperity and independence. The leading of the Potras were quite active in setting up the quarry as a cooperative, leading to even more prosperity. However, such entrepreneurship was not something that the communist regime could tolerate so a number of Potras were sent to forced labour.
