Beira Lake (/bˈɐjɾɐ/; Sinhalese: බේරේ වැව, translit. Bērē væva; Tami: பேரே ஏரி, translit. Pērē ēri) is a lake in the center of the city of Colombo in Sri Lanka. The lake is surrounded by many large businesses in the city. It initially occupied approximately 1.65 km2 (0.64 sq mi) of land 100 years ago and this has since been reduced to 0.65 km2 (0.25 sq mi) today due to various reasons. During the colonial era of the Portuguese, Dutch and the English the lake was used for a wide variety of purposes. It still retains its Portuguese name. It is connected to many intricate canals which provided an easy way of transporting goods within the city and suburban cities.[1]


The derivation of the name is uncertain, yet it was as recent as 1927 that ‘Beira Lake’ first appeared on maps. Before that, it was called the 'Colombo Lake' or just 'The Lake'.[1] One idea is that it got it's name from a Portuguese Engineer called 'Beira' who worked in constructing the lake[2] or from a Dutch Engineer called 'De Beer'.[1][2] The idea of De Beer is supported by a granite plaque which was recovered from the sluice of the lake, inscribed "De Beer 1700".[1]

Other idea is that it got named from the word 'Beira', which in Portuguese meant the 'Bank or Edge of the Lake'.[1] Another idea is that it got from 'De Beer', which in Portuguese meant the 'Anchoring Point'.[2]


The lake was built by the Portuguese to provide protection to Colombo from enemies, mainly local kings.

By 1518 Portuguese ruled over Colombo, but the increasing threats against Portuguese rule by King Vijayabahu VII and Sinhalese forces made them to look for better solutions other than their modern weaponry. One of such begun ideas was making of a huge moat around the fort.[2]

The construction of the moat started by digging the marshy land which was around the fort in all direction other than west (west of fort was Indian Ocean). But these works were demotivated by the size of it and the small amount of water in the marsh which was not enough to fill a lake. But a stream which flowed between Mount of Dematagoda and Mount of St. Bastian was discovered in this situation by Portuguese Captain Lopo de Brito, while he was chasing away another invasion lead by King Vijayabahu VII. After informing the officials at the fort about this stream, it was connected to the moat they have dug, creating Beira Lake.[2]

Then the lake has been completely connected with the sea from both sides, separating the Colombo Fort from mainland. All means of transportation between mainland and the fort have been done using boats. Original are of the lake has been 1.61 km2 (0.62 sq mi). Primary outflows then have been the Kayman Gates to the east and St. John Canal to west. It has been bordered from Mount of St. Bastian, Mount of Wolfendal and from Mount of Kochchikade. To the north and west of the lake have been the Portuguese forts.[2] The nature of the lake then has been described in Conquista Temporale Espiritual de Ceylão (1687) by Fr. Fernão de Queyroz:

"The lake around the City of Colombo is having a complete length of 10 ½ miles. It which had the the Mount of Lawrence was surrounded by a lagoon. In some places at summer time it was deep only to the waist, and was a lake which gave access to City of Colombo"

In 1578, Mayadunne of the Kingdom of Sitawaka attempted to cut of supplies to the invaders but failed to drain the lake. His son Rajasingha I (a.k.a. Sithawaka Rajasinghe) succeeded in 1587 to drain the crocodile infested lake by cutting off several canals but failed to defeat the Portuguese as they brought reinforcements from India through sea.[2]

After the Dutch laid siege and captured the lake it was expanded by reducing the fort by 1/3 of the previous and created several islands such as the Slave Island some of them were large enough to have a village and a plantation of 600 coconut trees. After the British took control they removed the crocodiles and developed the area surrounding the lake for recreational activities such as rowing and yachting. The area around the lake was popular for parties including a grand ball that was held to celebrate the news of British victory in Waterloo. Ceylon's first botanical garden the Kew Gardens was opened in Slave Island in 1810 to cultivate seedlings provided by the Royal Botanic Gardens Kew in London.[1][2]

By the 19th century land reclamation for development began and the land area of the lake was reduced, pollution also began to increase.[1]

Greater Beira[edit]

Lined with many large warehouses, reminiscent of its past when tea used to be transported to the port of Colombo on barges via the port access canal, the lake now is very quiet with many of the warehouses been abandoned.

With maximum length of 1 mile, the lake has been home to Colombo Rowing Club for over 140 years.

The Sri Lanka Exhibition and Convention Centre is located on the waterfront, further the People's Bank and the Inland Revenue Department headquarters are located in close to the lake.St. Joseph’s college Colombo, the only school in Sri Lanka to have its very own Rowing pier is situated on the banks of the Beira lake. The Associated Newspapers of Ceylon Limited is housed in the nearby "Lake House" building.

The lake with many government owned properties has been earmarked for development including a casino district on its McCullum road water front.

Flora and fauna[edit]

The lake is home to species of storks, pelicans, monitor lizards and various species of fish.


The lake gets its famous green color and unusually bad odour due to the result of pollution over hundreds of years and algae that is present in the water. The bad smell is mostly prominent during dry weather, due to the high rates evaporation and it fades off with the arrival of the rainy season

Beira Lake Restoration[edit]

The Beira Lake plays a major role in the Western Region Megapolis Project. Under the project the Beira lake is expected to be cleaned and developed with Singaporean assistance and private sector involvement. Waterways will be cleared by blocking illegal water outlets and sewerage lines into the lake and relocating settlements that dump waste to the lake in the area to social housing units.[3][4][5] Under the Megapolis plan after the restoration a Shopping district ,an Enternainment district and a promenade will be created in the area around the Beira lake alongside many hotels and mixed development projects.[4][6]
