[1] Farmleigh Bridge was added to the estate in the 1870s to carry electricity lines from the mill race turbine on the Strawberry Beds to the house.

As many of the house's features were commissioned by Lord Iveagh, visitors gain some insight into his character from the landscaped gardens, classical architecture, and sober symmetrical layout.

[2] Some notable visitors have been hosted at Farmleigh including the Premier of China, the Prime Minister of Ethiopia, the King of Malaysia, British Prime Minister Tony Blair, the Governor-General of New Zealand, Queen Elizabeth II of the United Kingdom, and U.S. President Joe Biden.

[2] In 2006 it was announced by the Office of Public Works (OPW) that the Steward's Lodge which is located in the grounds of Farmleigh had been renovated.

[6] Today Farmleigh is operated by the OPW and the estate and gardens are largely open to the public, with the house closed except for organised tours.

[8] The estate has also been used as the venue for the RTÉ proms, a public concert series that took place each summer in a large marquee erected on the grounds.
