Murcia Removes Urban Mural After Residents Report 10-Degree Temperature Increase in Homes

A striking 180-square-meter mural in Murcia, Spain, was recently removed after residents reported that its dark colors caused indoor temperatures to rise by more than 10 degrees. The artwork, which had adorned the entrance of the Carmen neighborhood for five years, was part of the city's ADN Urbano program, funded by FEDER. However, its black background and intense colors absorbed excessive solar radiation, turning the façade into a heat trap for nearby homes. ## The Impact of Dark Colors on Indoor Temperatures The decision to cover the mural was made by the building's community of property owners, who funded the operation. Residents had complained about unbearable summer heat since the mural's installation in 2020, with nighttime temperatures reaching 39 degrees. According to local sources, the dark tones of the artwork acted like a radiator, concentrating solar radiation and overheating the entire building. The conflict highlighted the tension between artistic value and livability. ## Artists Express Disappointment Nels and Kraser, the two Murcian artists behind the mural, were not consulted before the decision to cover it. They lamented the loss of a significant work, which they described as one of their most costly projects, involving over 80 kilograms of plastic paint and 150 spray cans. The mural depicted Hestia, the Greek goddess of the home, as a tribute to Murcia when it was named Spain's Gastronomy Capital. The artists criticized the lack of mediation by the city administration, suggesting that a prior agreement with the property owners could have prevented the removal. ## Municipality's Stance and Future Implications The Murcia City Council, which initially commissioned the mural, stated that the decision to modify the façade rested solely with the property owners. However, it did not clarify whether any maintenance agreements were in place. Kraser, one of the artists, noted that simply painting the wall white would not solve the underlying heat issue, though reflective treatments could have preserved the artwork. Moving forward, the artists plan to charge standard rates for future municipal projects, citing this incident as a lesson in the importance of clear agreements. ## A Symbolic Irony The mural's removal carries a symbolic irony: it featured Hestia, the goddess of the home, yet failed to protect the comfort of the residents behind it. Architects explain that large dark surfaces can act as radiators, exacerbating heat in adjacent buildings. The wall now stands painted white-a color recommended by architects to avoid similar problems-a stark contrast to the once-vibrant artwork that had become a local landmark.
