Ugly Infrastructure: Stifling the West's Future?

2025-05-19

This article explores the lack of aesthetic consideration in Western infrastructure. The author contrasts the beauty of Ireland's Mary McAleese Bridge with the ugliness of much other infrastructure, arguing that aesthetics aren't an added cost, but a key to improving quality of life and promoting social development. Examples of aesthetically pleasing infrastructure from around the world are cited, highlighting how the absence of beauty leads to public resistance and ultimately, massive economic waste, as seen with the UK's HS2 project. The author calls for prioritizing aesthetic design in infrastructure, integrating art to build a better future.
