One of Budapest’s most important buildings turns 100 this year and instead of serving as home for one of the city’s notable residents or being a monument that commemorates a renowned saint, it provides more than half of the city’s thermal heating and a part of Hungary’s electricity supply. Buda’s monumental Kelenföld Power Plant is the perfect example of how remarkably buildings were constructed more than a century ago, even industrial facilities. During an exclusive event, we managed to visit this immense edifice to see its design and find out how hot water comes out of our taps in Budapest.
