I learned about this place from stihotvoreniya
Korney Chukovskogo "Aibolit" in which he wrote:

OK, OK, I'll run,
Help your kids.
Only where do you live?
On the mountain or in a swamp?

We live in Zanzibar,
In the Kalahari and Sahara,
On mount Fernando-Po,
Where walks, Hippo-po
Along the wide Limpopo... ))

Thank you for the wonderful photos and a fascinating story about Zanzibar.
Good mood for the whole weekend, @always1success

With respect and appreciation, @Singa
