Restoration and construction work on the Rotunda started on Monday, 11 January 2016, following the official handover of the site attended by the representatives of the contractor, archaeologists, restorers, and the investor (Faculty of Mathematics and Physics, CU). In the opening meetings, the conditions and ways of securing the architecturally valuable components and archaeological findings were discussed, the course of implementation detailed, and photographic documentation of the original state of the site was made. Relevant authorities (building authority, heritage preservation bodies, labour inspectorate) were informed of the commencement of the works.
