Faces from the past
Where: 26 Haji Lane
MRT: Bugis
It is hard to miss the 15m-high man in a turban drinking chai in Haji Lane. He is spraypainted on the facade of The Singapura Club, a six-month-old restaurant that serves Asian and North Indian cuisine.
The work is by graffiti artist Ceno2, who is known for his photo-realistic human portraits.
He spent about three weeks to complete this artwork, working from 11pm to 4am daily.
Although the man is the most eye-catching character on the wall, the mural features other subjects, such as close-up faces of a Samsui woman as well as a Malay man.
Mr Jerry Singh, who owns The Singapura Club and commissioned the piece, says the elderly and historic characters reflect the heritage of the neighbourhood.
Passers-by love the work. Mr Singh estimates that between 100 and 200 photos are taken of it every day. He also gets many queries from tourists and locals about the mural.
Old days of Chinatown
Where: Block 4 Sago Lane, Block 5 Banda Street and Block 333 Kreta Ayer Road
MRT: Chinatown
Created by 500 volunteers from accounting firm Pricewaterhouse- Coopers together with 100 Kreta Ayer residents, this set of 13 murals draw on Chinatown's heritage and modern-day scenes.
Look out for details such as two men playing a game of chess (above) and an erhu player sitting on the steps of a shophouse.
Spread out around the Banda Street area, the murals are part of Colouring Banda Street 2015, a charity initiative by the accounting firm.
Its employees also donated daily necessities to elderly residents living in the one- and two-room flats in the area.
The murals were handpainted over six months, with the largest measuring 18.5m by 3.7m.
History in an underpass
Where: Elgin Bridge underpass, North Bridge Road
MRT: Clarke Quay
Enlivening the Elgin Bridge underpass are two murals celebrating the history of the Singapore River - in particular, the area around Boat Quay.
Unveiled last year as part of the SG50 celebrations, the works were created by students of Raffles Design Institute and feature a graphic, blocky style. Characters are depicted in flat, 2D shapes that look almost like computer icons.
The 27m-long, 2.19m-high murals stretch across the length of the underpass.
The Back To The Past mural features the trade activities and transportation that took place against the backdrop of Boat Quay shophouses, such as bullock carts and bumboats carrying goods.
The Early Days mural (above) focuses on the people working along the Singapore River, such as rickshaw pullers, merchants and labourers.
Ever-changing graffiti art
Where: Aliwal Arts Centre, 28 Aliwal Street
MRT: Bugis/Lavender/Nicoll Highway
At the back of Aliwal Arts Centre is a wall of artwork that changes every one to six months.
Right now, there is a black-and- white mural (above) featuring a woman peeling open her chest, by home-grown graffiti artist Kilas.
Some time later, it will be replaced by another work by another street artist or group of artists.
The wall is "managed" by street- art collective RSCLS, which has a studio in the arts centre. Other groups which have taken over the wall so far include duo Ink&Clog and graffiti collectives Zinc Nite Crew and Three Flare Krew.
Ms Natalie Tan, Aliwal Arts Centre's senior manager of place- making, says tourists and visitors often come specifically to see the works.
How often the graffiti art is renewed is an "organic" process and depends on "artists' schedules and inspiration", she adds.
Concrete reliefs at Skyville@Dawson
Where: Skyville@Dawson, 86 Dawson Road
MRT: Queenstown
Sleek, graphic and monochrome, these murals at Skyville@Dawson by comic artist Troy Chin (above) differ from the usual street-style art that adorn building walls.
These concrete reliefs, which have the simplicity of woodcut prints, are themed around life in the Queenstown area from its kampung times to the present day.
Ms Pearl Chee of architecture firm Woha, which designed the housing estate, says some panels "capture early life in the Dawson and Queenstown area, such as kampungs and fishing in the canal, and places that people remember in their stories and memories".
There are more than 50 concrete panels in the three-block estate, including about 30 lining the walls of a common walkway.
Chin, 39, is known for his series of graphic novels titled Resident Tourist, featuring a semi- autobiographical character who feels out of place in Singapore.
As this is his first mural commission, he learnt a lot about how a public artwork can interact with its surroundings.
"I didn't expect the shrubs to grow so high and partially block one of the panels. But I don't mind, it's supposed to be connected to the environment," he says.
Watch out for goats in Tiong Bahru
Where: In and around Tiong Bahru market, 30 Seng Poh Road
MRT: Tiong Bahru/Outram
In 2014, artist Ernest Goh created three murals at the Tiong Bahru Market for the Chinese Year of the Goat.
These billy goat paintings continue his animal-inspired series, which he started in the neighbourhood in 2013.
For many hipsters, the three chickens and two fish painted around the pre-war apartments and shophouses provided many photo opportunities over the years. But of these artworks, only one goldfish near the Tiong Bahru Post Office survives.
The images are printed on paper and then applied on the wall using a wheat-pasting method, where wheat flour and water are used as an adhesive. This, says Goh, 37, is "a cheap and fast way to put up murals", compared with painting or spray painting.
Asked about his subject matter, he said he wanted to depict animals that used to be found frequently in the kampungs in Singapore, such as the wandering chickens and fish in the longkangs.
Building's history on facade
Where: Goh Loo Club, 72 Club Street
MRT: Telok Ayer
In this artwork on the side of the 111-year-old Goh Loo Club, a Samsui woman "peels away" the wall to reveal a historic scene in the three-storey shophouse.
The mural works like a cross-section of a doll house. Looking in, one can see genteel, old-fashioned rooms decorated with lanterns, paintings and elaborate Chinese window screens.
The occupants are historical too, comprising men in long Chinese tunics and Western suits.
Painted by Singapore artists Benny Ong, Zhao Jian Wen and Didier Ng, this mural recreates what Goh Loo Club was like in the early days when it was a place where the local Chinese community and visiting dignitaries gathered. The mural's cast of characters include businessmen, Chinese revolutionary figure Sun Yat Sen and a Japanese soldier guarding a door.
The building underwent a major renovation in the interiors, which saw it clinching an Architectural Heritage Award this year.
