The Negombo Fish Market is interesting because it takes place right on the beach, fresh from fishing boats. Crowds of fishermen are seen untangling their fishing nets, playing with their kids, and stretching out miles of fish to dry in the sun on Negombo's shore. A must see place when you are in Negombo.

A grand old Catholic church built in the 18th century. St. Mary’s Church, Negombo is landmark edifice, a Roman Catholic church in the heart of Negombo. Its exterior surface is painted in pink colour. It is one of the largest cathedrals in Sri Lanka. Negombo has been influenced greatly by the Christian faith from the time it was occupied by the Portuguese. It is often called "Little Rome" in view of the large number of churches in the city. Construction of the church was started in 1874 and completed, after a long gap, in 1922. The art and architecture of this church and a few similar other churches in Sri Lanka demonstrate the cultural amalgamation of the European practice with Sri Lankan art and architecture during the early years of the 20th century. The church was built in neoclassicism style with columns and plain walls. Its ceilings are painted with alabaster images of many saints. The walls at the upper level are fixed with sculptures of religious saints. The unique paintings on the life of Christ on the ceiling were done by the N.S. Godamanne, a local Buddhist painter. The beauty of the paintings on the nave is described as "thunderous". A testator paid the cost of one of the altars, which was imported from Europe

The Hamilton Canal (also commonly known as the Dutch Canal) is a 14.5 km (9.0 mi) canal connecting Puttalam to Colombo, passing through Negombo in Sri Lanka. The canal was constructed by the British in 1802 and completed in 1804. It was designed to drain salt water out of the Muthurajawela wetlands. The canal was named after Gavin Hamilton, the Government Agent of Revenue and Commerce.

Negombo Fort was a small but important fort in Negombo, approx. 30 km (19 mi) north of Colombo, that was built by the Portuguese to defend Colombo. In its time the fort at Negombo was probably the next in strategic importance after Colombo, Jaffna and Galle. The original Portuguese fort was a weak structure, which was captured by Dutch forces commanded by Philip Lucasz, in February 1640.The Portuguese made several attempts to retake it before they were successful in December 1640. They then strengthened the fortifications and managed to defend the fort until it was recaptured by the Dutch, commanded by Francois Caron, in January 1644.The original bastions were destroyed by the Dutch cannons during the siege of the fort. The Dutch subsequently rebuilt it in 1672 however not on the usual square pattern, but on a pentagonal one, though it had only four bulwarks, the fifth was never constructed (possibly due to the cost). The fort was located on a narrow strip of land between a lagoon and an inlet of the sea. It was surrounded by a dry moat, and the gate was accessed via a drawbridge. In February 1796 it was occupied by the British without opposition. In the late 1800s the British authorities decided to demolish the fort and build a prison in its place, constructed from the stones of the fort.Today all that remains is a section of the eastern rampart with mounds at its northern and Southern ends, where the previous bastions existed, and an recessed arched gateway. Above the gateway is a slab of granite, with the date 1678 inscribed, surmounted by a high decorative gable. The site is still used as a prison by the Department of Prisons.
