Between 2006 and 2008, the interior of the laboratory of Electrical Drives classroom was remodelled and the room was changed into a lecture auditorium. At the back of the E-1 auditorium there is a permanent exhibition of historic electrical measurement equipment. The building of the Chemical Faculty – "Old Chemistry" The Chemical Institute (Chemisches Institut) building was one of the first built specially for Gdańsk University of Technology in 1900–1904. The main entrance is decorated with a set of symbols relating to the purpose of the building. Above the entrance arch there is a decorative cartouche (currently with the inscription "CHEMISTRY") crowned with a triangular open tympanum. The refurbishment of the north wing of the Chemistry A building, that includes the Chemical Auditorium and infrastructure rooms, was completed in 2010. Symbols of chemical elements The symbols of chemical elements are evenly spaced along the top edge of the facade in the side wings of the Chemical Faculty building. The 24 characters – heavily stylized abbreviations of the symbols of chemical elements – have been divided into 4 groups of 6 symbols each. The non-metals were placed on the west wing, while metals on the east one. The elements are depicted by the symbols used in the late 19th and early 20th century. Gdańsk Tech Chemical Auditorium The interior of the auditorium has regained its early 20th-century appearance following a renovation. The historic auditorium has retained 80 percent of the original fittings and interior design: the decorative wall paintings, decorative architectural elements of the arches, laboratory tables, chairs with back supports and desks. Stoneware laboratory sinks were also preserved along with the wooden windows – including the door handles, fittings and hinges – doors and the electrically controlled window shutters. Periodic Table The periodic table originally painted in 1904 and discovered during the renovation of the Chemical Auditorium reflects the knowledge of chemistry in the early 20th century.
