Antananarivo, often abbreviated to Tana, has a distinctively French flavor and atmosphere: French is widely spoken, and road as well as shop signs are mostly in French. The city is built on three levels. Dominating the city is the Queen’s Palace and associated Royal Village or Rova. Now a national monument, it was once the residency of the Merina Dynasty which, in the 19th century, united all Madagascar for the first time. On the lowest level is the market of Analakely. The Zoma Market, claimed to be the second-largest in the world and certainly worth a visit, is held daily. The Tsimbazaza Zoological and Botanical Garden is open Thursday, Sunday and holidays 0800-1100 and 1400-1700. The Tourist Information Office is nearby. It is wise not to wander too far after dark.
