Church of St John Aliturgetos
A medieval Orthodox church of the 13th–14th century in Nessebar — a peak of the picturesque style with alternating white stone and red brick; conserved, but no longer in use.
The Church of St John Aliturgetos, also known as St John the Unconsecrated, is a medieval Orthodox church located in the town of Nessebar. The building is an inseparable part of the town's Architectural and Historical Reserve, which is inscribed on the UNESCO World Heritage List, as well as among the 100 National Tourist Sites of Bulgaria.

Historical development and the origin of the name
The construction of the church is dated to the 13th–14th century. It owes its distinctive name Aliturgetos (from Greek — “unconsecrated”) to a popular legend, according to which one of the workers died during the building works. Under the strict church canons, a place where human blood has been shed cannot be consecrated. Despite this legend, there are sources indicating that services were nevertheless held in the building in certain periods.

The church ceased to function long before the beginning of the 20th century. Serious damage was inflicted on its structure during the devastating Chirpan earthquake of 1913.

Architectural features and artistic value
Although it is partially ruined, the Church of St John Aliturgetos is regarded by researchers as a remarkable example and a peak of religious building from the pre-Renaissance period of medieval Bulgaria. The building occupies an area measuring 18.5 by 10.25 metres.

Plan: The church is a typical representative of the cross-domed churches. It has a spacious narthex and a square naos, in the middle of which four supporting columns were originally raised, carrying a high and narrow dome.
Picturesque style of the façades: The exterior design marks the highest degree of development of the picturesque architectural style in our lands. Through a masterly alternation of white stone blocks and red bricks, complemented by decorative ceramic discs, complex geometric ornaments were achieved, resembling multicoloured embroidery.
Uniqueness of the details: Each of the façades has an individual and entirely different treatment. Best preserved and exceptionally striking is the eastern façade. It stands out with three articulated apses, richly decorated with elegant arcatures and slender niches.
Present condition
Today St John Aliturgetos is a conserved and restored, but non-functioning church. It holds the status of a monument of culture and remains one of the most significant sites for cultural and historical tourism along the Southern Black Sea coast.
This church offers a valuable insight into Byzantine and medieval Bulgarian building traditions.
