Fort Willem I, known in Indonesian/Javanese as Benteng Pendem Ambarawa (Ambarawa's Sunken Fort), is a 19th-century Dutch fortress in Ambarawa, Central Java, Indonesia. During the Diponegoro War (1827-1830), Colonel Hoorn, Commander of the 2nd Division, assigned to the crossroads at Bawen, instructed the construction of a logistical supply point, as well several military barracks, to give immediate supply and forces for the war, as Bawen is a vital junction connecting the cities of Semarang, Yogyakarta, Salatiga and Surakarta. As a result, several sheds, made out of bamboo, were built at this strategic point during the war.
