The construction of this medieval palace was initiated in 1442 to form a meeting place for merchants. The archaeological style has been influenced by several people through a range of various alterations and additions to the building.

The Duke’s Diwan is a time capsule of early 20th-century Amman, hidden in plain sight on the busy King Faisal Street. Built in 1924 as the city’s first post office, this Ottoman-era stone house later became the Haifa Hotel before heritage activist Mamdouh Bisharat ("The Duke of Mukheibeh") rescued it from demolition in 2001. Today, its creaking wooden floors lead through rooms frozen in Jordan’s past, complete with antique typewriters, sepia photos of camel caravans on dusty roads, and a balcony overlooking downtown’s metamorphosis. More than a museum, it’s a living diwan (gathering space): poets hold readings at the carved oak table, while artists riff under the Arabian archways. Admission is free, and the duke himself sometimes holds court, spinning tales of old Amman over cardamom coffee. Don’t miss the upstairs gallery, where rotating exhibits spotlight Jordan’s underground creatives.

This elegant arch, about 18 metres high, was erected at the entrance to the causeway atop the harbour in honour of the Emperor Traian. With its 2,000 years of history, this monument is well worth a visit.
