The development of digital technology has given us the ability to permanently preserve the historical and cultural information carried by architectural cultural heritage, which is a non-renewable and valuable historical and cultural resource. Digital technology provides a more convenient and efficient way of displaying and disseminating architectural cultural heritage, which is suitable for different geographical locations, cultural characteristics and preservation conditions, and enables the conservation of architectural cultural heritage to be completed with high quality and efficiency. With the continuous improvement of the digitization of cultural heritage, we should actively carry out the digital protection of architectural heritage, and always pay attention to the development and application of digital technology, and constantly explore and practice the new forms of digital technology in the field of architectural heritage protection.

Digital preservation is a new direction for the safeguarding of architectural cultural heritage. Through the systematic introduction of relevant digital technologies and the summary of experiences in the development practice, this paper explores the digital protection methods of architectural cultural heritage from the theoretical and practical operation level.
