Dublin is a very charming city.

1. Located on the east coast of the island of Ireland, Dublin is more than 200 km from Belfast, the capital of Northern Ireland. Dublin is Ireland's jewel city, where every brick and tile, from Trinity College to Dublin Castle, tells a story of the past. A perfect blend of classic and modern, it's the ideal starting point for exploring Ireland. 2. St. Patrick's Cathedral is one of the largest churches in Ireland. Its tower is 43m high. Originally built in 450 AD, it was gradually built up until the 14th century. Many famous people are buried here. Dublin Castle, built in 1204, is a symbol of Irish national independence and an important place to learn about the history of Dublin. 3. Trinity College and the Old Library: Trinity College is an ancient Irish university with a strong academic atmosphere, founded in 1592. The Old Library is a landmark building in Dublin, housing the Irish national treasure, the *Book of Kells*. Marble busts line the Long Room, which served as the inspiration for the library in the *Harry Potter* films. 4. The Spire of Dublin, originally named the "Monument of Light," is a giant, 121.2m-high stainless steel needle-shaped monument. Every dusk, the bottom and the top 12m of the Spire are lit up, like a beacon reaching into the sky, guiding the entire city in the night sky. It's a great place to take photos.
