Tripoli delves into the political and architectural history of Northern Lebanon, particularly focusing on an unfinished project by Oscar Niemeyer in 1962. Initially a symbol of Lebanon's prosperity, this grand vision was halted by the civil war in 1975, leaving the site with a dual legacy of architectural marvel and a traumatic past, now serving as a military storage rather than its intended purpose. The film blends architectural documentary with fragmented drama, reflecting the complex, disjointed narrative of the site, intertwined with violence and the uncanny.
