Malahide Castle (Irish: Caisleán Mhullach Íde), parts of which date to the 12th century, lies, with over 260 acres (1.1 km2) of remaining estate parkland (the Malahide Demesne Regional Park), close to the village of Malahide, nine miles (14 km) north of Dublin in Ireland.
The estate began in 1185, when Richard Talbot, a knight who accompanied Henry II to Ireland in 1174, was granted the 'lands and harbour of Malahide'. The oldest parts of the castle date back to the 12th century and it was home to the Talbot family for 791 years, from 1185 until 1976, the only exception being the period from 1649–60, when Oliver Cromwell granted it to Miles Corbet after the Cromwellian conquest of Ireland; Corbet was hanged following the demise of Cromwell, and the castle was restored to the Talbots. The building was notably enlarged in the reign of Edward IV, and the towers added in 1765.
The estate survived such losses as the Battle of the Boyne, when fourteen members of the owner"s family sat down to breakfast in the Great Hall, and all were dead by evening, and the Penal Laws, even though the family remained Roman Catholic until 1774.
In the 1920s the private papers of James Boswell were discovered in the castle, and sold to American collector Ralph H. Isham by Boswell"s great-great-grandson Lord Talbot de Malahide.
Malahide Castle and Demesne was eventually inherited by the 7th Baron Talbot and on his death in 1973, passed to his sister, Rose. In 1975, Rose sold the castle to the Irish State, partly to fund inheritance taxes. Many of the contents, notably furnishings, of the castle had been sold in advance leading to considerable public controversy, but private and governmental parties were able to retrieve some. Rose Talbot, one of the last surviving members of the Talbot family died at Malahide House, Tasmania in 2009. Her closest relatives, who married into the German surname Dietsch, travelled to Canada and the United States of America. Members of the Dietsch family still live in the USA and Canada today.
Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
