Meanwhile, in Zanzibar...

"Bit by bit, Zanzibar's fabled Stone Town is crumbling. Every year, a few more buildings collapse, leaving yawning gaps in the narrow, winding alleys lined with Arab palaces, Persian baths, British colonial offices, Indian shops and one-time slave chambers.

"Relentless sun, rain, wind and neglect have taken a toll on one of the world's cultural treasures -- the former capital of a trading empire stretching from Africa to the Middle East, Asia, Europe and the United States.

"About 85 percent of the more than 1,000 buildings show signs of structural decline, says Abdu Sheriff, a historian and former curator of national museums. Conservationists estimate at least 200 have fallen in recent decades, including three so far this year.

"Zanzibar, a semiautonomous archipelago off the cost of Tanzania, was once the center of a vast empire of Swahili city states stretching from Somalia to Mozambique.

"Through the centuries, the islands were colonized by the Portuguese, Omani Arabs made their capital here, and the British established a protectorate. They built fortunes on the slave trade and spices, making Zanzibar the leading exporter of cloves during the 19th century.

"Stone Town remains Zanzibar's commercial and cultural center, the seat of government, its main port and a major tourist attraction drawing more than 100,000 visitors annually.

"Its varied cultural heritage is preserved in coral stone walls and imposing wooden doors, whose intricate carvings reveal their owner's religion, wealth and status. It has been home to Arab sultans, Indian and Chinese merchants, European explorers and the late rock star Freddie Mercury."

What an odd footnote.
