The Goths and Aula near the village of Khan Krum
At 12 km from Preslav, four early antique churches from the second half of the 4th-5th centuries have been discovered within the Early Middle Age (aul) built in 822. They precede the construction of an aula about four centuries ago. One of the churches is richly frescoed. Fragments of frescoes with images of saints and elements of Christian symbolism are found in it. Inside and within the churches, graves belonging to local community leaders were explored. In them were found jewels made of gold, gilded silver and semi-precious stones. The comparative analysis of these finds shows that they belong to the style of the Gothic art of IV-VI century. They find parallels among the monuments of the Crimea, the Northern Black Sea coast, the Danube Roman provinces, Italy and Spain, where the Goths lived at various stages of the Great Migration era. The decorations from the Khan Krum village date from the second half of the 4th century to the end of the 5th century and reflect the different stages of Gothic migration on the territory of present-day Bulgaria: the arrival of the Christianized Arianas, led by Bishop Vulphila in c. in the 4th century, the passage of the visigoths to the south of the Danube River (after the Hunan invasion of 375-376) and the ostrogots who had freed themselves from the power of the Huns after Atylas death in 453. In comparison with the written sources the intensified preaching and enlightenment of bishop Vulphila (about 311-383) and his disciples, the finds from the village of Khan Krum testify that there was one of the spiritual centers of the Gazi-Aryan missionaries. It originated in the second half of the 4th century (probably still alive by Bishop Wulfilla) and existed until the end of the 5th century.
