The Spassky Cathedral, or the Cathedral of the Transfiguration, stands on the Val, the ancient detinets of Chernihiv. It is one of the oldest structures in Ukraine: along with Saint Sophia of Kyiv, it is among the few 11th-century temples that have survived to our day in their original volume. Once, this was the main temple of the Principality of Chernihiv and the burial vault of its princes.

The Cathedral Begun by Mstyslav
The temple was founded in the early 1030s by Prince Mstyslav Volodymyrovych of Chernihiv, the brother of Yaroslav the Wise. The chronicle for the year 1036 recounts the death of the prince and notes that the walls of the cathedral at that time had risen only "to the height of a horseman" — a man on a horse with a raised hand. The construction was eventually completed by Mstyslav's nephew, Sviatoslav Yaroslavych, no later than the mid-11th century.
Since then, Spas served as the cathedral church of the Eparchy of Chernihiv and retained this status until 1919. The founder himself, Mstyslav, was buried in the northeastern extension. Later, Sviatoslav Yaroslavych, his sons Oleh and Hlib, and other princes of the Chernihiv dynasty found their final rest here.
What to Look For
The cathedral is three-naved, with three semicircular apses in the east and five domes. The facades are almost without decoration, but take a closer look at the brick patterns: "fans", checkerboard fields, crosses, "suns", and a large meander on the western facade were laid out on the walls and the drum.

Inside, the side parts are separated from the sub-dome space by arcades on marble columns with stylized Ionic capitals. Such a Byzantine technique is nowhere else repeated in Old Ruthenian architecture, so Spas's marble columns are a true rarity. Similar capitals are known in Chersonesus and in Constantinople.

The cathedral survived the Mongol pogrom of 1239, fires, and several rebuilds. The first major restoration was carried out in the 1660s by Archbishop Lazar Baranovych. Later repairs changed the tops of the domes and towers, but the main volume of the ancient temple has been preserved.
Nearby on the Val
A few steps away stand the Borys and Hlib Cathedral and the building of the Chernihiv Collegium, and further on are the cannons on the edge of the Val, the Tarnovsky Historical Museum, and the view of the Desna. You can walk all these places along the "Along the Val and Tretiak" route.
How to Get There
The cathedral stands at 1-A Preobrazhenska Street, in the Val park in the center of Chernihiv — a 10–15 minute walk from Krasna Square. It is part of the "Ancient Chernihiv" National Architectural and Historical Reserve. Before visiting, it is worth checking the reserve's excursion schedule.
