Since 1976 up to the present, the Czech Institute of Egyptology at the Faculty of Arts, Charles University in Prague has conducted systematic researches at Abusir necropolis, located 25 km away from Cairo. However, uncovering of the mastaba of Ptahshepses took place already between 1960 and 1974. Apart from Egyptologists, also experts from various scientific and technical institutions participated in these works. In 1978 to 1981 and in 2002, geophysics and geological analyses of building materials became a part of this activity. In the recent period, also results of satellite photography were used in a large extent. Using all these tools, a number of tombs and temples were uncovered from both the period of the Old Kingdom (3rd to 6th dynasty) and the Late Period (6th century BC). The compared results of prospecting and archaeological uncovering on individual structures of Abusir necropolis document the usefulness of team cooperation during localizing the abovementioned types of structures in the arid conditions of Egypt.
