There are countless things to do and places to see in Dublin, Ireland. There are theaters, concerts, and movies, of course, but there are some very old, very interesting things there as well.
Trinity College, officially named the College of the Holy and Undivided Trinity of Queen Elizabeth near Dublin, founded in 1592 by Queen Elizabeth I, is the oldest illegal in Ireland. Oscar Wilde and Jonathan Swift are alumni of the college. Situated in the very heart of Dublin City, the college’s towering Gothic buildings and lush green draw visitors, as does the lavish history of the site. The college is one of seven ancient universities in Ireland and Britain, and is still a working college, is full of people and movement when classes are in session.
The college’s Old Library, which was built in the 18th century, contains an awesome collection of literature. The most valuable and famous of all the books in this library is the Book of Kells, an illustrated version of the gospels, including the Book of Durrow, the St. Gall Gospel Book, and and the St. had Gospels. It was created in approximately 800 AD, more than six centuries before Gutenberg invented the printing press, by Celtic monks. The monks filled the book with vibrant depictions of Jesus Christ, his apostles, and his followers. Borders of the pages are decorated with elite knots and other beautiful designs. The book was named for its original resting place, the Abbey of Kells, where the book resided for centuries.
Kilmainham Gaol, which opened in 1796 as the Dublin’s County Gaol, and it closed in 1924. In between, it housed militant rebels of the various Irish rebellions in 1798, 1803, 1848, 1867, 1916, 1919, and 1922. Some of them were executed at the Gaol. The Gaol also housed thousand if men, women, and even children for crimes such as murder and rape, and for petty offense including stealing food. And there were thousands more people who had been convicted of one crime or another who were held here while waiting to be moved to Australia. Today, it is a museum.
Dublin Castle was built in the early thirteenth century on the site of a former Viking settlement of Dublin, and from 1204 until 1922, it was the seat of government of the English and then the British administration of Ireland. Constructed on the orders of King John of England, this medieval fortress had four corner towers linked together by curtain walls, which were a medieval type of defensive walls. The castle was built on high ground. It served primarily as the residence for the Viceroy of Ireland, which was the British monarchy's representative to Ireland as well as the administrative and ceremonial center of Ireland.
It stood intact until April of 1684, until a major fire damaged a large part of the castle. Even so, it left much of the fortification survived to the point that most of the castle is still explored by visitors.
During the late 17th ad 18th centuries, the castle was essentially rebuilt in a manner which converted the medieval stronghold into a Georgian palace, with a huge suite of reception rooms, or state apartments, which were used for state ceremonies, balls, and banquets.
A chapel, called the Chapel Royal, was added in the early 1800s which provided a place of worship for the Viceroy and his family.
After the 1922 independence of Ireland and the removal of a viceroy from the country, the castle was given over to the Irish government and now serves as a government complex as well as a tourist attraction.
These are just some of the things to see and do in Dublin, Ireland. Many more are listed below.
