Aapravasi Ghat by Els Slots
I just visited this site a week before with my wife during our one week trip in Mauritius.
Actually I have went the palce twice, first day I can't find the entry and just took a picture due to Sunday.So I went to the site on Monday again.
I didn't know there is a World Heritage in Port Louis before, I just happen to meet the site while we walk through the main street.
