Trowulan is an archaeological site in Trowulan Subdistrict, Mojokerto Regency, in the Indonesian province of East Java. It includes approximately 100 square kilometres and has been theorized to be the site of the eponymous capital city of the Majapahit Empire, which is described by Mpu Prapanca in the 14th-century poem Nagarakretagama and in a 15th-century Chinese source. When it was the capital of the Majapahit Empire, the city was known as Wilwatikta, which is a name also synonymous with the empire's name.
