The site now occupied by Belfast City Hall was once the home of the White Linen Hall, an important international Linen Exchange. Plans for the City Hall began in 1888 when Belfast was awarded city status by Queen Victoria. This was in recognition of Belfast's rapid expansion and thriving linen, rope-making, shipbuilding and engineering industries.
Construction began in 1898 under the supervision of architect Sir Alfred Brumwell Thomas and was completed in 1906. Belfast Corporation, now the council, its their profits from the gas industry to pay for the construction of the Belfast City Hall.
The exterior is built mainly from Portland stone and is in the Baroque Revival style. It covers an area of one and a half acres and has an enclosed courtyard. Featuring towers at each of the four corners, with a lantern-crowned 53 m copper dome in the centre, the City Hall dominates the city centre skyline. As with other Victorian buildings in the city centre, the City Hall's copper-coated domes are a distinctive green.
The Titanic Memorial in Belfast is located on the grounds of Belfast City Hall.
References: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.
