The Paradise floor mosaic is from the apse of the St. Sofia basilica, located in Sofia, Bulgaria. It is property of the National Archaeological Institute with Museum at the Bulgarian Academy of Sciences (NAIM-BAS). It was entered into the inventory book on 13 March 1899 and is the first lifted mosaic in Bulgaria. In 1913, prof. Bogdan Filov published an article about the mosaic in The Sofia church St. Sophia book.

The mosaic measures 2.70 m by 2.60 m.

It is made of stone and coloured glass tesserae using the opus vermiculatum and opus tesselatum techniques.

In the centre of the composition, there is a large luterium with two doves. Under the luterium, there are two baskets with plants that are pecked by two more doves. Two cypresses entwined with vine scrolls (rinceaux) are symetrically placed at both sides. According to the Christian tradition, the scene symbolises paradise, with the doves representing the belivers' souls.

The mosaic dates back to the first quarter of the 4^th century.

The restoration's main goal was to remove the thick cement base. The weight of the mosaic and its base was 1200 kg, which was a major problem when it came to trasnporting the panel. After replacing the mosaic's old base with a new one, made of contemporary light materials, the total weight was reduced in half. The mosaic was restored and exhibited in the most appropriate manner.
