Great Synagogue

The Great Mosque of Constanța, also known as the Carol Mosque, was built between 1910 and 1913. Its name refers to King Carol I (1881-1914) who initiated the construction of the mosque, dedicated to the Muslim community of Constanta. Initially, the mosque was named "Carol I Mosque", then it was later renamed the Mahmoud II Mosque. The construction was carried out in the Egyptian-Byzantine style, with some Romanian architectural additions. It is the first building with reinforced concrete elements built in Romania.

The Church of St. Anthony of Padua was built in 1938 according to the plans of the Roman architect Simon (1900-1981). This neo-Romanesque church, which imitates the churches of northern Italy, replaces an old church from 1886. In 1944, when Soviet troops occupied the town, the church was put out of use and in the years to come it was vandalized. In 1947, the church was returned to the Catholics. Abandoned in the early 1950s, the church was restored in the same decade, then in the 1980s and in 2012.

The church "Saint Mina" was built between 1995 and 1997 according to the plans of the architect Nicolae Goga and is an imitation of the traditional style of Maramures. The furniture of the church was entirely carved in wood. The painting that covers it was done by the Bucharest painter, George Sorin Nicolae.
