Four years after the last incursion of the Turks of Evrenos-bei in Transylvania and beyond the mountains, where they were eventually defeated, in 1405 a royal decree decided that the Transylvanian towns had to be strengthened with massive walls. Although in the past the churches of the rural Saxons communities had been damaged by various incursions of the Tartars and Turks, their fortifications weren’t built after a plan, therefore only in 1427 we find out about a strong fortress in Prejmer, fortress in which all the inhabitants would survive to all the pagan attacks that would last several weeks.

Therefore, when the community of Kleinschenk, from beyond the river Olt, finished building the church in 1421, year inscribed on the west tower, the building wasn’t surrounded by the massive walls which would appear a few decades later. The place where the edifice devoted to the Holy Apostles was erected wasn’t chosen by accident near the Roman camp where the II Flavia Bessorum cohort had stationed centuries before. Because of this proximity, many of the spoliations from the garrison were embedded in the walls of the citadel, except the feminine mask that was to be discovered centuries later.

The hall-church has a massive belfry on the west side. The rectangular nave with a loft on the north side was covered with a ceiling; the choir made of a rectangular bay ending in a polygonal apse is vaulted with ogives. We find here an altar piece from 1868. A gothic tabernacle was preserved here, just like in the churches from Cincu or Apold.

If the interior is not very impressive in terms of planimetry or decorations, the exterior which is marked by the defense level, built on consoles towards the end of the 15^th century in a fachwerk system of wood and timber, above the choir, adds a special feature to the fortification system of the Saxon churches. Similar examples can be found in Drăușeni and Stejăriș.

In the mid-fifteenth century, a polygonal perimeter around the church was delimitated by high walls, doubled on the south and southwest sides, a part of the west side being separated by a wall in order to form a reduit. The entrance was defended by a tower, and other three massive ones were disposed along the curtain wall.
