The Dunsink Observatory is an astronomical observatory established in 1785 in the townland of Dunsink near the city of Dublin, Ireland.Its most famous director was William Rowan Hamilton, who, amongst other things, discovered quaternions, the first non-commutative algebra, while walking from the observatory to the city with his wife. The annual Hamilton Walk that commemorates this discovery begins at the observatory. He is also renowned for his Hamiltonian formulation of dynamics. In the late 20th century, the city encroached ever more on the observatory, which compromised the seeing. The telescope, no longer state of the art, was used mainly for public 'open nights'. Dunsink observatory is currently part of the Dublin Institute for Advanced Studies (DIAS). It provides accommodation for visiting scientists and is also used for conferences and public outreach events. Public talks on astronomy and astrophysics are given regularly at the observatory by professional and amateur astronomers. Stargazing events are also held using the Grubb telescope.

The townland has an area of approximately 1.7 square kilometres (0.66 sq mi), and had a population of 323 people as of the 2011 census.The townland is the site of Dunsink Observatory, where William Rowan Hamilton and Hermann Brück were directors. Built in 1783–1785, it is the oldest scientific institution in Ireland. The observatory houses a 12-inch (30 cm) refracting telescope which was built by Grubbs of Dublin using a French manufactured lens. It is situated on a hill 8 km northwest of Dublin's city centre, where the astronomy section of the School of Cosmic Physics in the Dublin Institute for Advanced Studies is located.The 1880 Definition of Time Act set the official time in Ireland to be Dublin Mean Time. This was computed as the time at Dunsink, which was about GMT-25m21. In 1916, another act moved Ireland to Greenwich Mean Time. Dunsink time is mentioned five times in James Joyce's novel, Ulysses.Formerly the location of "Dublin’s biggest landfill facility", Dunsink is also the site of a major unofficial Traveller encampment, the subject of considerable media coverage in 2007.

Ashtown Castle (Irish: Caisleán Bhaile an Ásaigh) is a tower house in the Phoenix Park in Dublin, Ireland. It was found hidden within the walls of a much larger and more recent Georgian building, the Under Secretary's Lodge also known as Ashtown Lodge, that was being used by the Papal Nuncio until 1978. At that time, the Lodge was deemed structurally irreparable due to dry rot. However, as the building was being demolished, Ashtown Castle was discovered. It has now been restored and forms part of the Phoenix Park Visitor Centre.It is thought to originally date from the 1430s, as it is built to dimensions that conform with a government policy of the time that offered £10 to those who built a castle for their own safety. The castle was later incorporated into the construction of Ashtown Lodge which was to serve as the official residence of the Under Secretary from 1782.

The Under Secretary's Lodge was formerly the Dublin residence of the British Under-Secretary for Ireland (the British Administration's chief civil servant). After the creation of the Irish Free State in 1922, the office of Under Secretary disappeared. The residence was rented by the Irish Free State to the Vatican for use as the Apostolic Nunciature (papal embassy). The Lodge was vacated by the Papal Nuncio in the mid 1970s, when he moved to a new purpose-built nunciature on the Navan Road in Dublin. It was intended to turn the Lodge into a Taoiseach's residence (residence of the prime minister of Ireland). But after some years' delay it was decided that the Lodge (in a politically unappealing Georgian style) was in too poor a state of repair due to dry rot to be converted and so was demolished. A preservable medieval tower house was found to be at the centre of the demolished Georgian building. It has been restored, and as Ashtown Castle it is used as an interpretative centre. Tours of Áras an Uachtaráin (residence of the President of Ireland) begin from the centre every Saturday. While it served as the Apostolic Nunciature, one of its most famous residents was Giovanni Montini, later Pope Paul VI, who worked as a young diplomat there.
