D.C. will join national parks across the country this weekend in honoring four centuries of African American history with a bell ringing.

The ceremony is set to take place on Aug. 25, 400 years to the day that the first ship of enslaved Africans arrived in Hampton, Virginia, then occupied by the British. The National Park Service has asked that parks nationwide ring bells for four minutes (one minute for each century of African American history) at 3 p.m. Eastern time.

Additionally, national park sites around D.C. will be honoring the day with special events, per a release from NPS.

• Carter G. Woodson Home: DC Strings will perform at 2:40, followed by the bell ringing and a tour of the Logan Circle site.
• Fort Washington Park: At the historic fort in Prince George’s County, visitors will participate in a moment of reflection and bell ringing.
• Frederick Douglass National Historic Site: In addition to the bell ringing, the site in Southeast D.C. will host a house tour and a group reading of Douglass’ 1852 speech “What to the Slave Is the Fourth of July?”
