Rosslyn Chapel, properly named the Collegiate Chapel of St Matthew, was founded on a small hill above Roslin Glen as a Roman Catholic collegiate church (with between four and six ordained canons and two boy choristers) in the mid-15th century.
The chapel, built 150 years after the dissolution of the Knights Templar, supposedly has many Templar symbols, such as the "Two riders on a single horse" that appear on the Seal of the Knights Templar.
Another notable feature of Rosslyn's architecture is the presence of 'Green Men'. These are carvings of human faces with greenery all around them, often growing out of their mouths. They are commonly thought to be a symbol of renewal and fertility, pre-Christian in origin.
