Dallas is remembering President John F. Kennedy on the 50th anniversary of his assassination. 

Hundreds of people from all across the globe braved the cold to attend the ceremony at Dealey Plaza.

The event featured a tolling of bells all across Dallas just after a moment of silence when the first bullet fired by Lee Harvey Oswald struck JFK.

Dallas also unveiled a memorial featuring the last lines from a speech Kennedy was planning to give at the Dallas Trade Mart the day of his death.

The John F. Kennedy Presidential Library and Museum is commemorating the late-president's legacy with an interactive website.

Titled "An Idea Lives On," the website is asking people of all ages to share their thoughts about the 35th president's lasting impact on everything from the arts to civil rights and education.

JFK's presidency was cut short by an assassin's bullets in Dallas 50 years ago today.  Visitors to the new website will be taken through a series of short video stories focusing on Kennedy's legacy.
