Chapter one
History of Mnemba
Mnemba Island lies just a few kilometres offshore from Matemwe Beach on Zanzibar's northeast coast. The surrounding atoll has been a protected Marine Conservation Area since 2002, and the island itself is home to a single ultra-luxury lodge and a resident population of green turtles that nest on its beaches.
