Topolog is a commune in Tulcea County, Northern Dobruja, Romania. It is composed of seven villages: Calfa, Cerbu (historical name:Hagiomer), FÃÂgÃÂraÃÂu Nou, LuminiÃÂa (historical names: Rum Ali, Urumbei – until 1925, Regina Elisabeta – until 1948, Elena Pavel – until 1964), MÃÂgurele, SâmbÃÂta NouÃÂ, and Topolog.
FÃÂgÃÂraÃÂu Nou ("New FÃÂgÃÂraÃÂ") was founded around 1880 by Mihai Popa Radu, a former captain in the Austro-Hungarian Army. Naming the new village after his hometown, he brought along seventeen families from Transylvania, part of a broader migration of Mocani.
