The GISB Parent Association is excited to host the popular GISB flea market on April 29, 2023, from 1:00 – 4:00 at the Upper Campus, 57 Holton Street in Boston. Take the opportunity to declutter your house and sell your old gems, or make a steal of a deal yourself. You can look forward to:

  • Browsing books, clothing, household items, toys, and more.
  • Enjoying homemade cake, waffles, and coffee
  • Clothing swap organized by the GISB Student Environmental Club
  • German book sale
  • Stocking up on GISB spirit wear & merchandise
  • Kid’s activities & crafts offered by the GISB student reps

Everybody is welcome! Last but not least, please do not forget to bring some cash. We are looking forward to seeing you there!


Be sure to bring some cash, and please note that parking is not available on campus. We kindly ask you to park in the neighborhood or at Artesani Park. For loading and unloading, the parking lot can be used briefly. Thank you for your understanding.

Volunteer & Cake Donations

If you can lend a hand on April 29, please sign up here. Donations of cakes are, of course, always welcome. Just bring any cake to the event. Please label it with your ingredients. Thank you!


Everyone is welcome to sell books, clothes in good condition, or household goods. There is no fee for kids selling their own goods on a blanket – Seller registration has closed.

View, download, and share the event flyer. For questions, please contact the GISB Parent Association.

How does the clothing swap work? It’s easy:

  1. Bring some clothes you no longer want but are still in good condition to the swap.
  2. Meet other people, see what they brought, and you can directly swap clothes with someone.
  3. Or just drop off your clothes for others to look at and take home.
  4. Everything that has not been picked up will be donated to a local homeless shelter and textile recycling center.
