The city has numerous monuments, historic buildings, sites of significance, and traditions related to the customs and history of the Central Highlands people. The city skyline is dominated by the Rova of Antananarivo. The nearby Andafiavaratra Palace was the home of 19th century Prime Minister Rainilaiarivony and contains a museum featuring historic artifacts of the Kingdom of Imerina, including items saved from the fire at the Rova. Downhill from the palaces is Andohalo square, where Merina kings and queens delivered speeches to the public. Tsimbazaza Zoo displays many of the island's unique animal species and a complete skeleton of the extinct elephant bird. Other historic buildings include the Ambatondrafandrana tribunal where Ranavalona I dispensed judgement, the second residence of Rainilaiarivony with its indigenous medicinal plant garden, the recently renovated Soarano railroad station, four late 19th century memorial churches built to commemorate early Malagasy Christian martyrs, the tomb of Prime Minister Rainiharo, and the early 20th century pavilions of the Analakely market. Open air markets include Le Pochard and the artisan market at Andravoahangy. The Museum of Art and Archaeology in the Isoraka neighborhood features exhibits on the history and cultures of Madagascar's diverse ethnic groups.
