BOSTONS first-responders have started an evening of remembrance in a makeshift memorial to the victims of the Boston Marathon bombing and marathon bombings that left more than 260 dead.

The event, which is expected to draw more than 1,000 people, will be held at Boston’s Red Sox stadium in the downtown core.

The organizers said Sunday they plan to offer free admission to those with tickets to the memorial, but those without tickets are free to attend.

The memorial, called “Bostons first responders and their families,” will feature a memorial plaque and a photo of a Boston firefighter and an unidentified Boston police officer.

The group is asking people to leave their shoes at home and pick up a copy of “The Big Red One,” the book by a Boston police sergeant that includes a portrait of an officer who died during the Sept. 11, 2001, terrorist attacks. 

Boston Police Commissioner Ed Davis said the event was meant to reflect the resilience of the city. 

“We’re in a very unique time where so many of our friends, colleagues and loved ones are here,” Davis said.

“I can’t tell you how grateful we are to have these people and to have a memorial here.”

The city is also mourning the victims, whose names will be announced on Monday. 

Davis said the memorial would feature the names of the officers killed in the bombings.

He said the names will also be on a plaque on the field of the stadium, which will also feature a tribute to the city’s first responders.
