In the southeastern part of the Great Assumption Monastery lies an interesting architectural complex consisting of two spacious chambers connected by a vestibule and covered by a common roof. From the vestibule, a covered passage leads to the refectory of the hospital church of Euphemia, and then to the square of the temple topped with a tent.

This complex, known as the "medicinal," is located next to the Svetochna Tower. The large hospital chambers were built by local masons under the guidance of Yakov Kostousov in 1643-1644. The impressive monumentality of the building is due to its elongated rectangular shape with massive walls and a high gable roof. The facades of this large structure, with large pediments on the ends, are almost devoid of decoration and appear quite austere.

In contrast to the hospital chambers, to the west of them is a small hospital church of Euphemia, built shortly after the chambers, in 1646. It sharply differs from other monastery churches with its tent style. Nevertheless, the architecture of the church of Euphemia shows a noticeable influence from the side church of Epiphanius, erected a year earlier, which maintains a connection with monastic traditions. The composition of the facades and the decor of these temples are largely similar.

The only difference is the completion of the church of Euphemia: above the three walls covered with kokoshniks rises a small polygonal tent with an onion dome on a low octagon, which does not stand out from the outside. The tent was originally open inside, and the refectory, unusually located on the southern side, is connected to the hospital chambers by a passage. Also noteworthy is the small single-arch bell tower of the Pskov-Novgorod type above the roof of the refectory.
