The Lost World Castle, Castle attraction in Sleman, Indonesia.

The Lost World Castle is a castle-shaped attraction in Dusun Petung, Kepuharjo, Cangkringan, Sleman, built in 2016 on 1.3 hectares to resemble Benteng Takeshi. It stands about 6 km from the summit of Mount Merapi and offers photo settings such as a cowboy garden, white clouds, a flying motorcycle, angel wings, a 3D waterfall, a flying carpet and artificial cherry blossoms.

The 2010 eruption of Mount Merapi destroyed many of the surrounding villages and left the slopes covered in debris and volcanic rock. In 2016, local residents founded this attraction to bring economic activity back to the area and give the damaged land a new purpose.

The walls are made from volcanic rock collected after the eruption, giving the site a raw and unusual look. Visitors can walk through decorated gates, painted walls, and photo spots inspired by Japanese television shows and fantasy worlds.

The site sits on a hillside with uneven terrain, so sturdy shoes and comfortable clothing are a good idea before heading in. Going in the morning tends to be more comfortable, as the sun can get very strong later in the day.

The name refers to the 2010 Merapi eruption that swept away Kepuharjo village and left its economy in ruins. Villagers discussed a tourism village and brought in Ayung, a local entrepreneur, to build the castle on 1.3 hectares in 2016. It stands about 6 km from the summit, inside the disaster-prone zone, and was briefly closed in February 2017 over permits.
