The U.S. has a wealth of iconic landmarks -- man-made monuments of such jaw-dropping beauty that it is hard to decide which one is the best.

Now TripAdvisor answers that question with its ranking of America’s most iconic landmarks.

The Travellers' Choice Attraction awards, announced Tuesday, picks the top travel spots in the U.S. and worldwide based on the millions of reviews and opinions from TripAdvisor travelers. Award winners were determined using an algorithm that took into account the quantity and quality of reviews for landmark and park attractions worldwide, gathered over a 12-month period.

The travel review website's ranking of world landmarks includes numerous religious sites, including Sheikh Zayed Grand Mosque in Abu Dhabi, U.A.E.; the Great Cathedral and Mosque in Cordoba, Spain; St. Peter's Basilica in Vatican City and Bayon Temple at Siem Reap, Cambodia, while many of the U.S. landmarks honor those who served in battle. 

For the complete list of winners from the 2014 Travelers’ Choice Attractions.
