The Real Mary King's Close is a historic close located under the buildings on the Royal Mile, in the heart of Edinburgh's Old Town. Hidden beneath the city for centuries, it is an underground warren of streets where real people lived, worked, and died between the 17th and the 19th centuries. These closes were partially demolished and buried under the Royal Exchange, now the City Chambers. Discovered years later, it provides a unique glimpse into the city's past. Stories of ghosts and unexplained events have contributed to its mysterious allure. The close is named after Mary King, a prominent businesswoman in the 1630s. Tours led by costumed guides provide an immersive experience, recounting tales of the close's former residents and their lives in Edinburgh's bygone days. While exploring the site, visitors can learn about the struggles during the plague, see historical dwellings, and discover the truth behind many myths associated with the close.
