Ombalantu Baobab, Heritage baobab tree in Outapi, Namibia

The Ombalantu baobab is a giant Adansonia digitata standing 28 metres tall with a circumference of 26.5 metres, beside the M123 road to Tsandi in Outapi. Its trunk is hollow for the first six metres, and a fitted door opens into a chamber that can hold about 35 people.

The Ombalantu baobab is estimated at about 800 years old. Its hollow trunk, open in the first six metres, served as a chapel, post office, bar, house and hiding place during Namibia's history; a military camp stood beside it during the Bush War. It was declared a national monument on 1 September 2011.

The tree is called Omukwa waaMbalantu in Oshiwambo and gives its name to the Ombalantu Baobab Tree Heritage Site. Since December 2004 the site has displayed the tree's history and its role in the Owambo community, alongside the story of Namibia's struggle for independence. Craftwork and souvenirs are sold at the site.

The tree stands beside the M123 main road from Outapi to Tsandi, in the Omusati Region. The site has a display on the tree's history and its role in the Owambo community, opened in December 2004. The trunk door gives access to the hollow, which holds about 35 people.

The trunk is hollow for its first six metres, and the opening cut into it lets visitors step inside. During the Bush War a military camp stood right beside the tree, which had already served as chapel, post office, bar and hiding place. It was declared a national monument on 1 September 2011.
