As with most areas of the United Kingdom, as far as I experienced, Dublin/Ireland also has quite overcast conditions. The city has quite a few historical sights and is well worth a visit.
-
Spire of Dublin … Made of stainless steel and 120 meters in height! 
The 1882 monument and statue dedicated to Daniel O’Connell ‘The Liberator’ … Daniel O’Connell was an Irish politician who played a big role in Catholic Emancipation. 
Trinity College … Established in 1592. 
Statue of George Salmon … George Salmon was a distinguished and influential Irish mathematician and Theologian. 
‘Sfera con Sfera’ sculpture at Trinity College … Not sure what it is meant to signify 🙂 
St. Patrick’s Cathedral … Around 800 years old! National Cathedral of the Church of Ireland. They have conducted tours at specific times. 
What is a trip to Ireland without trying Guinness? 🙂 
Dublin Castle … Earlier it was used as UK’s power center in Dublin. Nowadays it is an Irish Government Complex. 
There were some real good sand sculptures on display … @Irish Castle. 
Another angle of St. Patrick’s Cathedral … 
St. Patrick’s Cathedral … One solid Cathedral. It is supposedly the tallest Church in Ireland. 
River Liffey … It is a nice walk alongside the river. 
Some of the bridges across the River Liffey had some interesting architecture … 
Another view of the Spire of Dublin …
Adios!
