Paramaribo is the capital of Suriname and the main port. It is an attractive city with many colonial buildings although quite a few of them look a bit run down.
Fort Zeelandia now houses the Suriname Museum. The fort is in a good condition and is well worth a visit. Furthermore there are a few interesting buildings of a religious nature. There is the St.Peter & st. Paul Cathedral, two synagogues, one of the biggest mosques in the Carribean and some hindu temples in the Koningstraat- which means your out of luck if you are a Buddhist.
The Palmentuin and the Cultuurtuin are nice parks where you can spend a few hours relaxing.
