College Square is a mixed-use building development, under construction as of April 2024, in Dublin, Ireland.

[1] The site of the development was located close to or at what was originally the River Liffey estuary and adjacent to what was originally the Viking landing spot and marking spot known as the steyn of Dublin.

[3] The position was later the location of one of the Royal Dublin Society's first premises on Hawkins Street from 1796 until around 1816.

[5][6] In 2021, Marlet Property Group began the construction of College Square after a €270 million agreement with Apollo Global Management and Pimco was signed.

In 2020, An Bord Pleanála approved plans for a 10-storey residential tower on top of the office block,[7][8] which was then extended by one more floor in 2022, increasing the final height of the building from 78 metres to 82 metres.
