The house, which was demolished in the 1920s, was named for Marino in modern day Italy, which the Earl visited on his grand tour of Europe.

[1][2][3] The house was designed and constructed following Lord Charlemont's return from his Grand Tour of Italy, Greece, Turkey, Egypt and France.

The grounds of the house included the more famous folly, the Casino at Marino, constructed slightly later from 1755 onwards and completed around 1775.

Later, the Christian Brothers moved to the newly constructed St Mary's building from 1904.

The original Georgian entrance gate pillars (1770) designed by Sir William Chambers and Giovanni Battista Cipriani were relocated to Griffith Avenue and are still in existence today.
