The first one is a building with a portico consisting of parallel rooms arranged in a line and the second one with a complex layout is located to the north of it. The building with a portico is 22.60 m long and consists of three parallel rooms arranged in a line oriented east – west. The bases of the columns of the portico are located at 2.80 in front of the northern face of the building and measure 1.30 m by 1.30 m. The columns were square, built of ashlars, and measured 80 cm by 80 cm. A room, 3.20 m by 1.80 m in size, is added to the northern façade in the western end of the building. A path of stone slabs, which lead to the basin built of ashlars bonded with mortar, was situated in front of the second room of the main building. The building with a complex layout measures 12.70 m by 15.30 m and is located at 1.80 to the north of the portico. The building consists of nine rooms arranged in three lines. The western and the eastern rooms were 2 m wide, while the central rooms were 4.70 m wide. The pavement of stone slabs in front of the building with a portico and around the building with a complex layout is over 20 m long and is connected to the pavement situated to the south of the Archbishop’s Palace. The pavement was built over the remains of an earlier building destroyed during the construction of the palatial square. A water-conduit of terracotta pipes, 42 cm long and 16 cm in diameter, was discovered, leading to the building with a complex layout. At the end of the 11th – 12th centuries, 14 midden pits were dug over the debris of the architectural ensemble.
