For the first time in the borough's history, rainbow flags to support the LGBTQ community will sway through the crowd at Brooklyn's St. Patrick's Day parade.

The Brooklyn LGBTQ organization BILO will join dozens of groups marching through Park Slope and Windsor Terrace on Sunday.

Lisa Fane, a co-founder of BILO, says the organization wants to make sure that young people know that they have a place in the parade and the Irish community no matter how they identify.

The parade starts at 1 p.m. on Sunday and runs from Prospect Park West and 15th Street down to 7th Avenue and Garfield Place, then back to Prospect Park West.
