The so-called Hisham Palace, which was built in the late phase of the Umayyad rulership (661-750 CE), is located outside the historical city limits of Jericho in the West Jordan country, Palestine*.

 A very good introduction to the complex (research) history of the palace and a tribute to the excavator Dimitri Baramki (1909–1984) is provided through the article by D. Whitcomb and H. Taha https://muse.jhu.edu/pub/2/article/501742/pdf

A large portion of the finds—particularly the numerous, and in some cases highly unusual, stucco figures—are housed in the former Palestine Archaeological Museum in East Jerusalem; following the Israeli occupation in 1967, the museum came under Israeli control and was renamed the Rockefeller Museum.

*Jericho is located in the so-called A zone, the fragmented area under Palestinian administration, which makes up 22% of the area, which had been given by the UN partition plan in 1947 to the Palestinians: i.e. 49% of what was originally Palestine (until 1946), while 51% was intended for the emerging state of Israel.
