The Medway Megaliths have become heavily damaged and dilapidated since original construction, largely due to an intentional program of destruction in the late 13th century CE. They began to attract the interest of antiquarians in the late 16th century, who developed a number of erroneous theories about their origin, before later being scientifically investigated by archaeologists in the late 19th century. Local folklore has also grown up around the monuments, which came to be interpreted and used as sacred sites by contemporary Pagans in the latter 20th century.
