The document discusses regeneration plans for the decaying old city of Tripoli, Libya. It outlines the historical development of the city from ancient times to present. It then categorizes existing buildings based on architectural significance and proposes restoration techniques. These include using compatible reversible contemporary technologies, restricting cement materials, and addressing structural weaknesses and degradation through stabilization and repairs. The plans aim to restore the old city's architectural heritage while meeting new functional requirements.
