[2] The amphitheatre itself was constructed in one of the old coquina quarries used to supply building materials for St. Augustine and the Castillo de San Marcos.

[4][5][6] The Pulitzer Prize winning playwright Paul Green was commissioned to write a play to be performed at the amphitheatre.

The result was Cross and Sword: A Symphonic Drama of the Spanish Settlement of Florida,[7] a musical reenactment of the first years of St. Augustine's existence.

Also in 2019, the Amp is ranked #2 amphitheatre in the United States and #3 worldwide according to leading concert-industry publication Pollstar Magazine's 2019 Mid-Year report.
