Mizil has three historic Orthodox churches. The oldest, dedicated to the Holy Trinity, dates to the late 18th century and is in Fefelei. Another one, dedicated to John the Baptist, is in the town centre and was built in 1857. The building is cross-in-square in form and Byzantine and Gothic in style, with Renaissance touches. Its original painting was lost; a restoration took place in 1916. The iconostasis is sculpted out of linden wood and covered with gold leaf in folk art fashion. A third church, consecrated to the Dormition of the Theotokos and located in the town square, is from 1865. Among its sacred objects is a wooden blessing cross featuring silver filigree work and twenty-four red gems; this is from the end of the 19th century and appears to be the work of an anonymous artist from the Russian school. Additionally, there are four 19th-century roadside crosses, two of which are considered historic monuments by the Culture Ministry.
