Old Dispensary

With its peppermint-green latticework balconies and sculpted clock tower, this 19th-century charitable dispensary is one of the most attractive landmarks on the waterfront. It was built by Tharia Topan, a prominent Ismaili Indian merchant who also acted as financial adviser to the sultan and as banker to Tippu Tip, Zanzibar’s most notorious slave trader. You’re free to wander through the interior, which now accommodates offices. In the airy courtyard on the ground floor is the Abyssinian's Steakhouse restaurant.
