The Orthodox Church of Transfiguration of Jesus (Spas) is located north-east of the Old Town. It was the first Orthodox church built in Lublin, constructed out of wood in 1447. The next iteration was renovated in brick in 1607 and was 'dedicated' in 1633. In the 17th century, the building passed several times between Orthodox church to the Ruthenian Uniate denomination and vice versa, which resulted in numerous reconstructions and changes in the church’s décor. Between the years 2002–2003, the original Renaissance ornaments of the barrel vault of the presbytery were uncovered in the form of paintings depicting the Holy Spirit, cherubs and seraphs and archangels. They are accompanied by stucco in the form of plaques, rosettes and winged angel heads. Fragments of the 17th-century polychromes depicting the crucifixion are preserved on the western wall of the nave. A precious element of the church's furnishings is the late Renaissance iconostasis (1st half of the 17th century) with icons dating back to the 16th and 17th century. The oldest is the icon showing the Virgin Mary Falling Asleep, originating from the mid-16th century.
