The 'Hitler House' refers to a semi-detached property in the Port Tennant area of Swansea, Wales, which gained global notoriety in 2011 after a photograph of it went viral on social media. The building became a prime example of pareidolia—the human tendency to see faces in inanimate objects—due to its slanted roof resembling a side-parted hairstyle and the dark lintel over the door mimicking a toothbrush mustache. Since its discovery by Charli Dickenson, the house has become a staple of internet culture, used in memes to personify buildings or joke about unfortunate architectural coincidences. It remains one of the most famous examples of accidental resemblance in the digital age, often paired with captions about suspicious neighbors or inanimate objects with bad attitudes.
