The Sidi Darghut Mosque stands inside the old medina near the Red Castle and takes its name from Darghut Pasha, the 16th-century Ottoman corsair commander and governor of Tripoli. His tomb is incorporated into the mosque complex, making it a pilgrimage site as well as a place of worship.
The mosque's architecture reflects the Ottoman period, with a characteristic square minaret and tiled interior. The building has been restored at various points but retains its historic character. It is one of several important Ottoman-era mosques clustered in the northern part of the medina near the castle walls.
