In the middle of the 16th century, one Hans Fock moved from the north German city of Lübeck to Estonia, which was then coming under the control of Sweden. Around 100 years later, Queen Christina, shortly before her abdication, elevated Fock’s descendants to the Swedish peerage. After Sweden’s decisive defeat by Peter the Great at the Battle of Poltava in 1709 and the subsequent annexation of Estonia to Russian rule, Henrik Johann Fock moved first to Malmö and then to other parts of Sweden, where through marriage he came into possession of an estate. His heir, Jacob Constantin Fock acquired further property, including land at Råbäck in the county of Skaraborg; it is from this place that the family’s title, Baron de Robeck, derives. His son, Johan Henrik Fock, enjoyed a colourful career, including fighting against the British army during the American War of Independence, before moving to England where in March 1789 he married Anne Fitz-Patrick, heiress to a Galway landowner: four months after the wedding, by an Act of Parliament Fock was naturalised as a British subject under the name ‘John Henry Fock, called Baron de Robeck.’ The couple’s son, John Michael Henry Fock, after serving under General Sir John Moore in the Peninsula Wars, settled in Ireland where in 1820 he married the Hon Margaret Lawless, daughter of Valentine Lawless, second Baron Cloncurry. Famously, her parents had divorced after Lord Cloncurry had successfully sued Sir John Bennett Piers for criminal conversation with his wife. Alas, it proved to be a case of ‘like mother, like daughter’ and in 1828 the de Robecks were divorced after the baroness was found to be having an affair with Lord Sussex Lennox, a younger son of the fourth Duke of Richmond (the couple subsequently went on to marry and have three children). Baron de Robeck married a second time and in due course acquired a house in Dublin’s Merrion Square which at some date in the early 1850s he elaborately redecorated. 

Like its neighbours, 40 Merrion Square dates from the late 18th century and has a three-bay plain brick facade. Its interior was presumably decorated in similar style to those on either side, with neoclassical plasterwork and white marble chimneypieces. However, as mentioned already, the house underwent something of a transformation in the mid-19th century when occupied by the third Baron de Robeck. Here the two first-floor reception rooms were redecorated in elaborate Louis Quinze style, the walls covered with thin panels filled with pendants, urns, leaves, ribbons and musical instruments. Some of the panels were also filled with mirrored glass while pedimented roundels were inserted over the doors and, in the rear room, the central oval of the ceiling painted with a trompe-l’œil sky. The architect responsible for this scheme is unknown, although Christine Casey has suggested the Belfast firm of Lanyon, Lynn & Lanyon since soon afterwards it was commissioned by the fourth baron to design a new country house, Gowran Grange in County Kildare. He may have been inspired to do so by the unfortunate death of his father, the man who had undertaken the refurbishment of 40 Merrion Square. Aside from his residence in Dublin, the third baron also rented Leixlip Castle a few miles outside the city. While staying there in October 1856, he disappeared, his body only being found 11 days later; it would appear the baron, who had gone down to the edge of the river Liffey below the castle to see the Salmon Leap, had slipped and drowned. 

In the period after the third baron’s death, 40 Merrion Square served various purposes. During the First World War, it housed the Irish War Hospital Supply Depot, and at the time of the Easter Rising in 1916, it was transformed by Dr Ella Webb into an emergency field hospital capable of treating 50 patients. Later in the last century, the house’s neighbour, 39 Merrion Square, became the British Embassy until burned by rioters in the aftermath of Derry’s Bloody Sunday in January 1972. By that date, the state-owned Electricity Supply Board already owned 40-43 Merrion Square and the same body subsequently acquired and restored No.39. Various alterations were made to the buildings, not least openings made at different levels, allowing internal movement from one house to the next. A lift shaft was inserted to the rear of No.41 and the party walls between rear gardens largely demolished, with much of the ground covered in frankly prosaic buildings and sub-stations. In 2019 the ESB offered the quintet for sale as a single lot, bought two years later by a development company which has since undertaken a scrupulous restoration of the whole property, so that it now provides flexible workspaces for a variety of businesses. Today’s pictures show the first floor rooms of 40 Merrion Square before and after this recent refurbishment.
