Colombo Town Hall (GPS: 6.91562, 79.86347), as opposed to the Old Town Hall, is an imposing neoclassical building completed in 1927. It faces the Viharamahadevi Park. The white-domed Town Hall is said to have been modelled after the Capitol Building of Washington, D.C.
I passed by the new Town Hall when I was visiting the Viharamahadevi Park with fellow members from AsiaExplorers. We were on our final day in Sri Lanka, and were sights around Colombo.
