The artwork was created by artist and paramedic Charly Helyar who lives in the town.
General Situation, as the artwork is known, is a 65m2 illuminated painting which covers a shopfront in the square.
The installation is located next to the non-profit TACO! gallery and is part of the growing number of artworks across the town.
Charly’s work was commissioned by Peabody, who are leading the regeneration of Thamesmead. Making culture part of everyday life is a key part of their long-term plan to improve, grow and look after the town.
Reflecting on her work, Charly said: “I created this work about people doing ordinary, human things. I was reflecting on love, war and displacement – on how people persist, caring for those they love, and surviving despite everything.
“Without light we cannot see. My mum going blind played a role in why I began illuminating my paintings and that sparked my current fascination with illumination.
“This time I wanted to make a large illuminated painting to brighten Cygnet Square during the winter months, while celebrating people’s ability to endure and care for each other, no matter the circumstances.”
Adriana Marques, Head of Cultural Strategy for Thamesmead, said: “We’re so pleased that Cygnet Square will be lit up by Charly’s vibrant installation that speaks so powerfully about resilience.
“Her artwork is an example of our ongoing partnership with residents and the growing community of creatives who are increasingly making Thamesmead their home.
“Together, we’re working to make culture a part of everyday life for local people. It’s great to have yet another exciting exhibition to add to the growing body of art and culture across the town.”
Peabody’s cultural support continues with Turner Prize winner Jasleen Kaur set to unveil Thamesmead’s first permanent public artwork later this year. Jasleen was commissioned to create this piece by the community-led Thamesmead Creative Studio.
General Situation will be free for the public to view from Thursday 16 January until Sunday 23 February.
