Brown Willy is a hill that can be found in the county of Cornwall, the southernmost county of England. The hill supposedly gets its name from the Cornish Bronn Ewhella, which translates as “highest hill.” This is likely due to the fact that Brown Willy stands 420 meters (1,378 ft) about sea level and is the highest point in Cornwall. The hill is also known for the “Brown Willy effect,” a local phenomenon in which heavy rain that has developed on Brown Willy travels downwind causing showers in lower areas. The effects of this phenomenon can be serious flash flooding and dangerous amounts of rainfall, causing widespread damage.
In 2012, local visitors to the hill campaigned to have the name changed due to the “giggle factor”—but the name remains unchanged today. Interestingly, Brown Willy is widely regarded as sacred by UFO followers, who visit the hill annually. These followers believe Brown Willy was supercharged with what they call “holy energy.” We can only hope that this is a myth, and Brown Willy does not explode.
