Saturday, April 15, marked the fourth anniversary of the Boston Marathon bombings.

  • Saturday marked 4th anniversary of Boston Marathon bombings
  • City of Boston honored victims, survivors of attacks
  • 121st Boston Marathon takes place Monday

Three people were killed and 260 others were injured during the attacks four years ago, but to this day, the city remains Boston strong.

A mix of celebrations and memorials occurred all weekend in Boston. Hundreds of people came out to remember and honor those lost and to show their support for survivors.

A bell rang out Saturday, marking the exact time the bombs hit the Boston Marathon on April 15, 2013.

The city honored the victims at the iconic finish line on Boylston Street on what is now “One Boston Day.”

The city plans to have a permanent memorial at the finish line.

Roseann Sdoia, one of the survivors who lost her leg in the bombings, threw the first pitch at the Red Sox game Saturday where they played the Tampa Bay Rays.

Despite the tragedy and loss, the city of Boston has come together, and refuses to let fear win.

Runners and spectators headed out Monday for the 121st Boston Marathon.

One returning athlete is Katherine Switzer, who made history by pinning on an official race bib and running in the 1967 Boston Marathon when the race was a male only event.

This is the 50th anniversary since she ran the race.
