Shugborough Inscription

The Shugborough inscription is a sequence of letters - O U O S V A V V, between the letters D M - carved on the 18th-century Shepherd's Monument in the grounds of Shugborough Hall in Staffordshire, England. It has never been fully explained, and has been called one of the world's top uncracked ciphertexts. These letter are found on a monument that was built in the mid-1700's. The painting contains a rustic arch and shows a woman and three shepherds. There are many theories revolving around these strange letters but have cracked the code or have evidence that support them.
