The Transfiguration Church in Kovalyovo was built around 1345. The southern annex is thought to have been designed as the burial vault of the Zhabin family. The church was notable for the frescoes created in the 14th century. During the Second World War, between 1941 and 1943, the church was destroyed. After the war, the ruins were conserved. In the 1960s, fragments of the frescoes were restored. Only 16 square metres originally survived, but the restorers (led by Alexander Grekov and Valentina Grekova) managed to retrieve about 160 square metres of frescoes from the debris. In 1970, the church was rebuilt to a design by Leonid Krasnorechyev.
The church is constructed in brick, and has one dome. It has a single apse and four square columns. This design is typical for pre-Mongol Novgorod churches. There are two auxiliary chapels of different size flanking the main building from the south and from the north. The south chapel has a set of limestone crosses inserted in the walls. The system of vault roofing features three semicircular wall gables (zakomara) which hark back to the pre-Mongol period. The pillars are square rather than circular or octagonal, as was typical for the 14th century.
The frescoes, created ca. 1380, covered the apse, the inner surface of the dome, the southern and the northern walls of the church, some of the pillars, and the interior of the western chapel. They were sponsored by Afanasy Stepanovich and his wife. The frescoes are thought to have been painted by a team of Balkan (possibly Serbian) painters. Their static and hieratic style has little in common with other Novgorodian frescoes of the period; but it shares similarities with the older Byzantine tradition. The total area of the frescoes was 450 square metres.
The interior of the dome was filled with images of the prophets. But it is the images of warrior saints that predominate. This is usually explained by the fact that in the 1370s the Grand Duchy of Moscow, with the support of other Russian states, was preparing to fight against the Golden Horde, culminating in 1380 with the Battle of Kulikovo. There is also the first Russian image of the dead Jesus Christ in the tomb.
References:Stobi was an ancient town of Paeonia located near Gradsko. It is considered by many to be the most famous archaeological site in North Macedonia. Stobi was built where the Erigon (Crna River) joins the Axios (Vardar), making it strategically important as a center for both trade and warfare.
Stobi developed from a Paeonian settlement established in the Archaic period. It is believed that in 217 BCE, Philip V annexed Paionia during his campaign against the Dardani who had entered Bylazora, the largest Paeonian town.
The city was first mentioned in writing by the historian Livy, in connection with a victory of Philip V of Macedon over the Dardani in 197 BC. In 168 BC, the Romans defeated Perseus and Macedonia was divided into four nominally independent republics. In 148 BC, the four areas of Macedonia were brought together in a unified Roman province. In the reign of Augustus the city grew in size and population.
