Dublin residents have been asked to "not be alarmed" by an archaeological dig that is taking place at a major historical site in the northside.
Experts will conduct archaeological testing at St Anne's Mansion in Raheny for three days starting Tuesday.
The latest project hopes to find how much of the subsurface remains of the Victorian mansion has survived.
Experts will open two trenches across the main area of the mansion under the south mound while recording information and backfilling.
The dig has been financed by Dublin City Council and is being carried out by Archaeology and Build Heritage Ltd.
A council spokesperson said on Twitter: "There is an archaeological dig beginning today in St Anne's park so please do not be alarmed if you see digging in the park today or over the next couple of days. For all necessary information please see images below."
The large Italianate-style residence, which is locally known as The Mansion, was built in 1873 by Elizabeth and Benjamin Lee Guinness.
It was inherited by their son, Sir Arthur Edward Guinness, in 1868 and expanded the gardens planting evergreen oak trees and pines along the main avenue and estate boundaries.
His wife, Olivia Charlotte Guinness, or Lady Ardilaun, transformed the grounds into French chateau-style gardens with eclectic influences of the Victorian era and the horticultural expertise of her Scottish gardener.
In December 1943, the main residence was destroyed by the fire and the ruins were demolished in 1968.
The only part of the residence that survived were the Tudor "Red Stables".
