The Institute of Architectural History and Theory at Tianjin University's School of Architecture was established in 1997, with its history dating back to the Department of Architecture of Tianjin Vocational College of Industry and Commerce, founded in 1937 (one of the predecessors of Tianjin University's School of Architecture). Since its establishment, the institute has been rooted in the practical courses of Chinese ancient architectural surveying and mapping, which have been passed down for over 70 years by predecessors. Adhering to the principles of inheriting tradition, constant innovation, and seeking truth from facts, the institute has continuously delved into the fields of ancient Chinese architectural history and theory research, heritage documentation, research and conservation of modern architectural heritage, and practice in cultural relic architectural preservation. It has achieved fruitful results in teaching, scientific research, practice, and international cooperation and exchange, and has developed into a high-level talent cultivation and research center with international reputation.
