Indra Patra Fort

Indra Patra Fort is a historic coastal fort located in Ladong Village, Masjid Raya Sub-district, Aceh Besar Regency, Aceh, Indonesia, about 19 kilometers east of Banda Aceh. Believed to have been built in the 7th century during the Hindu Lamuri Kingdom and later strengthened by the Aceh Sultanate under Sultan Iskandar Muda to defend against Portuguese attacks, it is regarded as one of Indonesia's oldest forts and an important example of pre-Islamic heritage on the northern coast of Sumatra.

Visitors can expect a compact coastal fort complex with thick stone walls, bastions, arched gateways, and a central well within an open courtyard. The fort sits near the shoreline overlooking the Strait of Malacca, surrounded by Ladong village and coastal vegetation. Visitors can walk along the walls, explore the interior grounds, view information panels about its history, and take photographs of the historic stone architecture and sea views.

Believed to have been constructed in the 7th century during the Hindu Lamuri Kingdom as a coastal defense fort, making it one of the earliest forts in Indonesia. Later restored and strengthened in the 16th-17th century by Sultan Iskandar Muda of the Aceh Sultanate as a military stronghold to defend the northern coast of Sumatra against Portuguese incursions. The fort demonstrates pre-Islamic architectural techniques using mountain stone and lime.

Represents the transition from Hindu-Buddhist to Islamic period in Aceh and is protected as a cultural heritage site (Cagar Budaya) by the Ministry of Culture and provincial authorities. It serves as an educational site illustrating early Acehnese history, traditional defense architecture, and the region's long-standing maritime importance.
