The Hempstead Historic District and Hempsted Houses in New London will be bustling with activity over the next couple of weekends.

This Sunday, people can take a free walking tour of the district, which is one of the Whaling City’s first African-American neighborhoods. This walk is part of the Connecticut Forest & Park Association’s CT Trails Day 2021.

Reservations are recommended through Eventbrite, with same-day registration allowed if capacity hasn’t been reached. Participants need to arrive 10 minutes before the 2 p.m. start time to check in, and everyone must wear masks and adhere to socially distancing guidelines.

Then, on June 11 and 12, the site will celebrate Juneteenth. At 6 p.m. June 11, Joseph McGill, who is founder of the Slave Dwelling Project, will lead a community campfire discussion. His work involves preserving slave dwellings and their history.

On June 12, from noon to 4 p.m., the Hempsted Houses will be showcasing music, dance, activities and crafts for kids. McGill will speak, and Tammy Denease will portray Joan Jackson, whose oldest son, Adam, was an enslaved farmer at the Hempsted House for more than three decades.

All visitors must wear masks.
