Broken Tiles, Healed Minds: How London's Mosaic Artists Are Piecing Lives Back Together

There’s something quietly radical happening in the parks and alleyways of East London. While the city rushes past, groups of people sit together arranging broken glass and ceramic tiles into sprawling, intricate mosaics—and in the process, they’re mending something far more fragile than artwork.

The Hackney Mosaic Project, founded by architect-turned-artist Tessa Hunkin, started almost accidentally. Hunkin spent time walking through Hackney, the London borough with more parks than any other in the city, and noticed a hidden corner in Shepherdess Walk that felt like it needed something. When she encountered a mental health recovery group in Westminster, a realization struck: the slow, repetitive work of building a mosaic—sorting shards, nipping tiles, pressing each piece into mortar—could be profound therapy. Over the past 15 years, what began as an experiment has transformed into something far more meaningful than public art.

The work demands intense concentration. Like embroidery or knitting, the steady rhythm interrupts negative thought patterns, quieting the internal noise of trauma and stress while building confidence. Participants include children, recovering addicts, people navigating serious mental health challenges, and neighborhood residents. They work side by side, creating something visible and permanent from broken fragments. As Hunkin, now 72, puts it:“It gives people a holiday from their head. It is a simple task that requires concentration and produces something at the end, so it is never time wasted because you can see where your time has gone.”

The installations speak for themselves. Shepherdess Walk features expansive Roman-inspired mosaics covering walls and pavement, depicting East London life across seasons—from local flora and fauna to modern figures clutching mobile phones. All of Hackney’s parks appear on two massive walls, immortalized in tile. The Hounds of Hackney Downs Park showcases 50 whimsical dog portraits, celebrating the neighborhood’s everyday characters. At River Place Health Centre in Islington, vibrant floral designs transform concrete benches into gathering spaces where over 100 local patients contributed to the work. These aren’t gallery pieces meant for the elite—they’re woven into the fabric of neighborhoods where people actually live.

What makes the project’s impact resonate isn’t just the artistry. It’s the metaphor embedded in every installation: thousands of broken pieces assembled into resilient works of art. For dozens of Londoners navigating PTSD, depression, and addiction, those mosaics become external proof that fractured things can become beautiful, that time and effort matter, and that community—the act of sitting beside another person and building something together—has healing power. Tessa Hunkin didn’t set out to revolutionize mental health treatment. She simply recognized that broken fragments, when arranged with care and intention, transform into something whole.
