Today is Juneteenth, the federal holiday recognizing the end of slavery in the U.S. in 1865. 

Banks, courts, post offices and most schools will be closed today in Massachusetts, along with state and local government offices and libraries. 

A celebration of the day is being held today in Brookline, where a Juneteenth block party is being held.  Events are also planned at the Museum of Fine Arts and Isabella Stewart Gardner Museum in Boston to mark the holiday.
