Dublin has a wide variety of attractions to explore including churches, historic buildings, museums, art galleries, parks and gardens. It’s a city rich in history and throughout the ages, art and literature have also played an important part on its cultural development. One of the best ways of discovering some of the most interesting sights is to take a hop-on hop-off sightseeing bus tour, which run every 10-15 minutes and stop by the major attractions of the city. http://www.dublinbus.ie/your_journey/sightseeing_tours.asp
