The central district of Roseau is tightly packed with small and large houses and even larger modern concrete structures. There is little green or open space in the city; there is even less today, as many of the courtyards that were once commonplace are giving way to office space. The district is, however, framed in every direction by natural elements. The sea and the river provide water elements while the Botanical gardens and the Government House gardens frame the city with green space. These elements are rare in the Caribbean. No other centre in the region has such extensive botanical gardens with such central location, and the Roseau River is among the largest that flow through any Caribbean capital.
