A particularly important residential complex of 23 medieval settlements lies in the northeastern mountainous part of Corfu, at the foot of the highest peak of mount Pantokrator (absl. 906m.). The settlements, others abandoned and some with continuous habitation until now, are typical examples of urban and religious architecture and art, as enshrined and developed in numerous rural settlements of the island.

The settlements were first mentioned in literary sources in 1347A.D. in a document of priest and a monk Anthimos Peritheioti, which refers to the founding of the monastery of the High Pantokrator, on top of the mount Pantokrator.

One of the 23 medieval settlements in the northeast part of the island is Old Sinies. Today, the settlement is abandoned. Nevertheless, for almost five centuries it was a well-organized and self- sufficient small provincial residential complex. The settlement (460 to 486m. absl.) is located in a protected area with particularly intense relieves. This kind of geomorphology along with the steep mountain ridges, the intense natural slopes, the existence of streams and rugged hillsides, has been the key to the spatial organization of the settlement, which was developed in separate residential units with no clear boundaries between them. The central core of the town is defined by a main road. Right and left of this road smaller streets are developed, with upward and downward slopes leading to houses which are storey or single floor constructions, typical of traditional Corfiot rural architecture. They have simple and austere facades with small openings for ventilation and room lighting. Internal spaces are austere too. Most of the houses are “closed type houses” without balconies, having the main entrance to the narrow or the wide side of the building. The external staircase, which leads to a covered terrace on the second floor, is a common characteristic feature in storey houses in Old Sinies and generally in Corfu.

The settlement also includes three single-room temples, St. Theodore Stratilatis, St. George and the Holy Trinity temple, which preserve fragments of post-Byzantine frescoes. This kind of frescoes are the most representative specimens of art, which are found mostly in the province, far away from the urban center of Corfu.
