The
Round Church (,
Kragla tsarkva), also known as the
Golden Church (Златна църква,
Zlatna tsarkva) or the
Church of St John (църква "Свети Йоан",
tsarkva "Sveti Yoan"), is a large partially preserved
early medieval Eastern Orthodox church. It lies in
Preslav, the former capital of the
First Bulgarian Empire, today a town in northeastern
Bulgaria. The church dates to the early 10th century, the time of
Tsar Simeon I's rule, and was unearthed and first archaeologically examined in 1927–1928.
