Tourists wandering through the streets of Belize City appreciate some of its quaint, wooden colonial architecture, reminiscent of the British colonial times. However, many have been destroyed by the hurricanes that have severely damaged much of the island. Regardless, these colonial houses are distinct with red roofs and white wooden walls. There are also Clapboard houses, which are colorful festively painted homes, hoisted on top of stilts.

The main sites with colonial structure are the Government House, the Anglican St. John’s Cathedral, and the Paslow Building which houses the post office and the Magistrates' Court.

St. Johns Cathedral is one of the most notable sights in Belize city, located on Albert Street. Built in 1812, it is the oldest Anglican Cathedral Church in Central America as well as the oldest building in Belize city.The building is built by slaves with bricks that were originally ballasts used to stabilize the hulls of European sailing ships.

Opposite the Cathedral, the Government House is a well preserved, white colonial building. The government House was built originally in 1814 to serve as the residence of many British colonial governor-generals .

The Paslow Building is in the center of the city, containing the post office and lower courts. It was named after a slave owner, Thomas Paslow. The Supreme Court Building is another landmark built in a classic British colonial style with a dome topped clock tower. This building is on the site where the original courthouse was built in 1818.

At the entrance of the harbor, the Lighthouse at Fort George point is a tomb as well. Since it was constructed with the money from Baron Bliss, the 5th baron of Portugal, he requested to be buried in from the lighthouse.
