Dublin's Ha'penny Bridge is well known to locals and visitors alike, built in 1816 to span the River Liffey it has carried pedestrians for over 200 years.

Dublin is home to many fine parks, the best known being St. Stephen's Green and Phoenix Park.
But there are many of these fine green spaces in the city, some with more colour than just the lush green grass such as here at Saint Patrick's Cathedral on a sunny day.
