Nativity Church is the earliest Arbanassi church. It consist of a naos (a man's department), a narthex (a women's department), a gallery running alongside on the north and on the west, while on the eastern side there is a chapel to "John the Baptist".
    There were several costructing stages in the building of the church. The present day naos was originally a church on its own. Its painting was completed in 1597. The composition of: "The Judgement Day" and "Nativity" date back to those times. The painting of the woman's department was completed in 1638. There, both the walls and the arches were painted. The composition there from self-contained cycles and themes: Mother Mary's Ascension, Jesse's tree, The Judgement Day. Jesse's tree composition follows the Biblical stories about Christ's predecessors. The presence of the antique philosophers and ancestors (Homer, Aristotle, Plato) in this scene was inspired by the humanistic tendencies of the time. The themes of Mother Mary's Ascension and of the Judgement Day testify to the great interest taken in the cosmogenic issues, the genesis and history of mankind. The chapel to John the Baptist was painted in 1632. The themes were taken from the life of its patron John the Baptist. The iconostasis is one of the earliest examples of woodwork in Bulgaria. Most of the paintings in the gallery were made in 1649. They are grouped in a calendar sequence of "Menelogue" and represent stories from the New and Old Testaments and The Seven Oecumencial Councils. The thematic cycles in the gallery are united in the scene of the "Vain Life in a Vain World" or the "Wheel of Life" with the zodiac signs. The paintings in the naos depict the Feasts, the Passions and Wonders of Christ. The paintings were completed in 1681.
