The Nanmyin Tower is the only remaining building of the original Palace of Ava. The watchtower was built in the early 19th century and stands 27 metres (89ft) high. Inwa was the capital of Burma for nearly 360 years, on five separate occasions, from 1365 to 1842. So identified as the seat of power in Burma that Inwa (as the Kingdom of Ava, or the Court of Ava) was the name by which Burma was known to Europeans down to the 19th century.
