Southend City Jam is the UK’s largest free street art festival, bringing together a global community of artists to transform the city into an open-air gallery. Since its launch, the event has grown into a major celebration of creativity, attracting hundreds of local, national, and international artists who bring colour and energy to over 100 walls across the city centre and seafront.

​

A joint venture between Southend-on-Sea City Council and renowned local street artists Ster.UPC and Ekto.1, the festival was born from a shared vision to turn Southend into a vibrant hub for urban art. What started as an ambitious idea has now become an annual highlight, drawing in thousands of visitors who come to witness large-scale murals, live painting sessions, and immersive art experiences.
