Olives, opera and a climate-neutral goal: How a mural in Greece won ‘Best in the World’

The southern Greek city of Kalamata, historically celebrated for its premium olives and Mediterranean allure, has achieved global artistic recognition. A monumental mural transforming opera legend Maria Callas into a powerful allegory for the city has been honored as the 2025 “Best Mural of the World” by Street Art Cities, an international platform dedicated to urban art.

This distinction emerges from a deliberate urban strategy rather than mere artistic coincidence. City officials, led by Deputy Mayor Vassilis Papaefstathiou for strategic planning and climate neutrality, conceived the mural as a visual manifesto for Kalamata’s ambitious goal to become climate-neutral by 2030. The artwork serves as an accessible representation of complex initiatives including sustainable development, agricultural innovation, and local economic resilience for its 73,000 residents.

Artist Kleomenis Kostopoulos, 52, executed the visionary piece, explaining that the mural titled ‘Kalamata’ uses Callas allegorically rather than literally. Instead of a conventional operatic portrait, he created an earthy, grounded depiction connecting people to their land through symbolic elements: native birds, agricultural products, and tree branches representing both roots and growth. Her dress embodies the “bloom and fruition” of Kalamata’s blessed terrain.

The creation process presented significant challenges, requiring approximately two weeks of intensive work spread across a month due to weather interruptions. Kostopoulos employed brushes, spray paint, and a cherry-picker to complete the massive installation.

Beyond aesthetic achievement, the mural has become a civic focal point generating multiple benefits. It has enhanced tourism promotion and stimulated discussions about public art’s role in urban spaces, with additional building owners expressing interest in hosting similar works. The artwork also strengthens local identity at a critical time, as southern Greece faces increasing climate pressures including heatwaves, droughts, and wildfires that threaten the olive groves central to the regional economy.

The Callas connection resonates deeply with locals—though born in New York to Greek immigrants, her father originated from a village south of Kalamata, making her a beloved native daughter. This bond is institutionally recognized through the Maria Callas-named alumni association at the local music school and a dedicated exhibition at the cultural center.

Community response reflects profound pride, with tourism educator Dimitra Kourmouli expressing “immense pride” in the recognition. Officials and the artist hope the award will catalyze broader appreciation for public art’s cultural, social, and economic benefits throughout Greece, serving as a springboard for meaningful conversations about art in public spaces.
