Aapravasi Ghat, a small complex of buildings located on the seafront, served as the island's main immigration depot for indentured labourers from India. The highlight of a visit is the Beekrumsing Ramlallah Interpretation Centre, which hosts kids' activities. You'll get the most out of your visit if you ring ahead to book a (free) guided tour. Otherwise, some of the original stone buildings remain and there are strategically placed life-size models of the immigrants.
The ghat was listed as a World Heritage Site by Unesco in 2006 for its important role in the island's social history. And while it may not look like much at first glance, this site resonates with Mauritians across the island. Britain pioneered its indentured-servant scheme in Mauritius and from 1849 to 1923 over half a million immigrants were processed here before being shipped to various plantations or other colonial islands. Today, almost 70% of Mauritius' citizens can trace their roots back to Aapravasi Ghat.
