ARCHAEOLOGICAL EXPLORATIONS IN PLISKA (Stanislav Ivanov –stanislavivanovarh@gmail.com) The site is situated between the Palace of Khan Krum / The Throne Palace, the Palatial Basilica and the Fortified Palace (the Citadel). Parts of two buildings were discovered. Building No. 2 is situated along the southern wall of the Citadel. Building No. 3 is situated between the Palatial Basilica and Building No. 2. The buildings consisted of parallel pair of rooms arranged in a line. They were built of ashlars, uneven stones and fragmentary bricks bonded with mud. Judging from the coins, the buildings date to the first half of the 11th century. The floor levels in Building No. 2 were removed and constructions of the capital and post-capital periods of Pliska were discovered below. Part of a sunken-floored house, which lay over a posthole that was c. 50 cm in diameter, was explored in square 137-M. Postholes, which preceded Building No. 2, were discovered. Four storage pits, containing materials of the 10th – 11th centuries, were explored. The foundations of a monumental building were discovered in squares 137/153/160-O-P. It was c. 9.50 m wide and was situated alongside the brick fortification wall of the Citadel. The building was constructed of ashlars bonded with mortar and dates to the 9th century AD. A secret subterranean passage was documented in squares 137/153/160-N. Places for stirring mortar, probably related to the building of the brick fortification wall of the Citadel, were discovered. A trench of a water-conduit was documented.
