on the main square The first written mention of the village is from 1567 as
Zepwyz. In 1602 it was recorded as
Szépviz ("beautiful water"). Its original Romanian name derived from the Hungarian toponym as
Ciuc-Sepviz which was Romanianized to its current official name in 1919. According to tradition, the village's original name was
Szépmező. According to
Balázs Orbán, it was founded during the reign of
László I as a community of border guards for the defense of the Ghimeș pass, on the eastern border of the
Kingdom of Hungary. The Roman Catholic chapel was built before 1694 by the Bíró family. The Roman Catholic church was built in 1892. The village administratively belonged to
Csíkszék, then, from 1876 until 1918 to the
Csík County in the Kingdom of Hungary. In the aftermath of
World War I and the
Hungarian–Romanian War of 1918–1919, it passed under Romanian administration; after the
Treaty of Trianon of 1920, like the rest of Transylvania, it became part of the
Kingdom of Romania. During the interwar period, the commune became the seat of
plasa Frumoasa in
Ciuc County. In 1940, the
Second Vienna Award granted
Northern Transylvania to Hungary and the commune was held by Hungary until September 1944. The territory of Northern Transylvania remained under Soviet military administration until March 9, 1945, after which it became again part of Romania. Between 1952 and 1960, the commune fell within the
Magyar Autonomous Region, between 1960 and 1968 the Mureș-Magyar Autonomous Region. In 1968, the region was abolished, and since then, the commune has been part of Harghita County. ==Demographics==
