Royal Palace Museum, UNESCO World Heritage palace museum in Porto-Novo, Benin.

The Royal Palace Museum is a UNESCO World Heritage building in Porto-Novo that holds royal regalia, ceremonial objects, and crafted items within its historic rooms. The architecture itself is part of the collection, with walls and structures preserving the building techniques and style from the past.

The palace belonged to the kings of Hogbonou in the Avassa quarter of Porto-Novo; the name Honmè means "inside the gate" and by extension designates a palace. It became a museum of the former royal residence of King Toffa, and on 31 October 1996 the palace and its surrounding district were entered on the UNESCO World Heritage Tentative List in the cultural category.

Honmè, or Honmey, means "inside the door" and by extension designates a palace. Part of the 2.5-hectare site is kept as a sacred place where ceremonies are still held. The reserve holds about 230 objects, including cult objects, musical instruments, pottery, asen portable altars, furniture and photographs of royal family members.

The location sits in an older part of the city and is reachable on foot, though streets can be narrow in places. It's best to arrive in the morning when it's cooler and there are fewer visitors around.
