ARCHAEOLOGICAL EXPLORATIONS IN AUGUSTA TRAIANA (Maria Kamisheva – maria_ivanowa@abv.bg) The site is situated in the northwestern part of Augusta Traiana, close to the fortification wall. In 1997 a triangle fortification tower was explored to the west of the site and in 2005 part of the fortification wall was discovered. Two shafts of the water-supplying system of Augusta Traiana were explored in 2006. The first shaft measures 1.40 m by 1.55 m and is built of bricks bonded with mortar. The second shaft measures 85 cm by 90 cm and is 40 cm in depth. It is built of bricks bonded with mortar and its inner side is plastered with mortar. Presumably, it was a distributing and deposition shaft. The water-conduit that begins from the deposition shaft was discovered. The water-conduit is oriented northwest – southeast and two segments of it were explored: the first one is 62 cm in length and the second one is 2.07 m in length. The water-pipes are 32 cm in length and 13 cm in diameter.
