All online tourists are welcome: Google has launched a virtual tour of the island prison where Nelson Mandela was held for 18 years.

As part of Google’s tour of Robben Island prison colony off the coast of Cape Town, online visitors can roam the cells and explore guard towers from a computer or smartphone, Mashable reports.

Robben Island, which has served over time as a leper colony, a mental hospital, and a maximum security prison built to hold civil dissidents like Mandela, is now a United Nations World Heritage site. Mandela spent 18 years there for opposing Apartheid.

Google also features historical exhibits like the theater where Abraham Lincoln was shot, Aushwitz concentration camp, and the site of the D-Day invasion of Normandy.
