Údol is a predominately ethnic Carpatho-Rusyn Greek Catholic village located in the former Saros County of the Austro-Hungarian Empire in present day Stara Lubovna District of the Slovak Republic. In 1427 the village was named Wyak which later evolved into Újak. This name was changed by the Communist Government takeover in 1948 to Údol. The village of Údol is still referred to as Újak by residents to the present day. The Greek Catholic Church of Saint Dimitry, the Martyr was built in the year 1866, and remodeled in 1888 and 1943. Prior to 1866 there was a wooden church at a location below the existing church.
