There is a built- up yard on the south of the Small palace in which there are two buildings. The formation of this south- western yard which is an inseparable part of the Palace complex because of its location happened no earlier than the end of the 9th- 10th century. The coin of the Byzantium emperor Leo the 6th (886-912) found in the construction level is a good chronologic marker about that.
Building 1 is situated in the northern part of the yard next to the southern façade of the Small palace. Its entire built up area is 252 sq.m. The building is a long chain building which is developed from west to east with length of 36 m. divided in seven rooms. The building’s length is seven meters from north to south. Its parts are divided by parallel dividing walls. The building’s chain plan is known from many other buildings in the early medieval architecture and in Preslav itself. It was possible to reach the yard and the building by horse which we can judge from the equipped slanting ramps.
There is no doubt the building used to be a temporary residential building. There are findings which relate to offering food and drinks on the table from its initial period i.e. from the time it was used for its main function and designation.
It is highly probable it used to be one of the so called pavilion type buildings- a building in yards and cities related to the ruler’s palaces, for relaxation and contemplation or for welcoming guests.
Building 2 was erected in this yard simultaneously or almost simultaneously with the first one. It is situated 20 m on the north of the southern façade of building 1. It has the same orientation of its long axis. Namely its eastern part is erected over a platform hanging over and jutting out a platform on the south of the palaces. The terrain of building arrangement in the equipment prepared this way shows an idea of planning in advance in this part of the palace center. The bases form a rectangular planned building with longitudinal axis east- west. There is a big rectangular hall on the east and entrance on the west. The 5 cm. thick plaster skim in the floor’s western part shows that it was probably covered with marble plates in opus sectile.
This building has special functions of triclinia or pavilions for receptions in the palace complexes of the East and West. Obviously both buildings have the similar and adding functions which caused their closing in one and the same yard.
Most probably they are buildings of two types which in Constantinople palaces are called triclinium- a building with a huge hall for receptions of different nature. The formation of the complex of the south- western yard is not only a matter of forming the palace town’s center but also a necessity. The prince’s and king’s residential town needed buildings with different functions and this need was already proven in the Constantinople palace life. Bulgarian rulers also needed separately isolated halls and pavilions in the common system of the palace design and which used to be the role of both buildings on the south- western terrace and probably other yet unknown buildings.
In addition we have to mention that the northern wall of building 1 is on the foundation of the early Preslav military camp. The eventually constructed Aul is rectangular planned with sizes 103 X 147 m. directed east- west. It most probably appeared in the beginning of the 9th century and extended to south and east on a later stage it did not exist at the announcement of the new capital.
