History

Mezhyrich belonged to the Ostrozkyi family, and each generation of the family left its own layer here. As early as the late 14th and the 15th century a wooden Trinity church stood next to the Ostrozkyi castle. According to M. Blyzniak, around 1460 Prince Ivan Vasylovych Ostrozkyi (†1465) built a masonry church in its place, which also had a defensive role. Wikipedia links the construction of the present church to the endowment of Prince Kostiantyn Ostrozkyi of 12 March 1523; construction lasted into the 1530s. The designer is unknown; he is thought to have been the same builder as that of the Epiphany Church in Ostroh.

At the beginning of the 17th century Janusz Ostrogski turned the monastery into a Franciscan friary. In 1606–1610 defensive galleries with gun loops were built above the church, and the western and altar parts were covered with Gothic rib vaults with Renaissance ornament; by 1612 the courtyard was surrounded by ranges of buildings, walls and towers. Paweł Grodzicki is named as the architect of the monastery buildings, though with reservations. The Franciscan friary became one of the most powerful Catholic centres in Volhynia. In 1850, 20 friars served here.

Fires in the mid-17th century and the great fire of 1854 damaged the domes, ceilings and wooden structures. In 1866 the Russian authorities dissolved the Franciscan friary: on 23 September the church was sealed, on 19 October it was handed over to the Orthodox clergy, and it became an Orthodox parish church; the main altar dedicated to the Holy Trinity was consecrated on 13 November 1866. In 1972–1978 the monastery was restored with the participation of the architect Olena Hodovaniuk. In 1991 the church became a monastery church again.

The day differs in the sources: 2 July ^[2] or 3 July ^{[7, 14]}; the year 1386 in OrthoChristian ^[15] is an error. ^{[2, 3, 6, 7, 14]}

3. Late 14th – 15th century

   A wooden Trinity church stood next to the Ostrozkyi castle; a masonry one was later built in its place. ^{[6, 7, 14]}

   Janusz handed the Holy Trinity Church over to the Franciscans and rebuilt the complex as a fortress monastery: two-storey ranges of cells were added to the church, and the courtyard was enclosed by walls with corner towers.

According to Wikipedia, in 1606–1610 defensive galleries with gun loops were built above the church, and the western and altar parts were covered with Gothic rib vaults. In 1612 the church and friary were opened. ^{[1, 3, 6, 7, 14, 15]}

5. Early 17th century

   The author of the monastery fortifications is believed to be the military engineer Paweł Grodzicki, builder of the royal arsenal in Lviv. ^{[1, 13]}

Lost and restored

Architecture

The church is almost square in plan, with three lower apses, pointed windows and stepped external buttresses. It combines the Old Rus tradition of the five-domed church with late Gothic Western European features. The sources give the number of pillars differently: Wikipedia names four, the website “Castles and Churches of Ukraine” six. Inside, the ornament is executed in sgraffito.

Below are two elements of the church: in a photo and in a drawing. The drawings show the form, not exact dimensions.

Stepped buttresses

The buttresses rise almost to the top of the main volume. They take the thrust of the vaults and at the same time give the church a stern, fortress-like silhouette.

Five domes

The five domes stand on octagonal drums. According to Wikipedia, at the beginning of the 17th century the drums were partly hidden by flat-roofed walls, and the domes lost their original proportions; later an uncharacteristic “star-patterned” covering appeared.

The wall and towers

The courtyard is enclosed by a brick wall — according to the website “Castles and Churches of Ukraine”, 1.5 m thick and up to 8 m high. At the corners stand two-tier towers, hexagonal in plan, with loopholes (Wikipedia describes them as three-tier, with an attic in the third tier). Symmetrical two-storey ranges adjoin the church on the north and south: service rooms below, cells above. The gate tower-belfry has not survived.

Stone and material

The church and the monastery buildings are built of brick and sandstone; the wall around the courtyard is of brick, about one and a half metres thick. Inside is sgraffito, a technique in which the ornament is scratched through layers of plaster. Franciscan altars of the 18th century were later partly reused for the iconostasis.

Mezhyrich explains well why defensive architecture does not have to be crude. A buttress here is both structure and the rhythm of the facade; the wall is both protection and a frame for the church. When a support does two jobs at once, it stops being a superfluous detail.

On columns, pilasters and supports in a church, see the columns and capitals section. Another church that knew how to defend itself is the Intercession Church in Sutkivtsi.
