A Hogwarts Halloween

Registration is NOW OPEN for
A Hogwarts Halloween at Blackstone Library!

Children attending one of four available daytime sessions will get the feeling they truly have entered the halls of Hogwarts. Upon arrival, children will be escorted by Prefects to the Great Hall, where they will be greeted by Professor McGonagall. From there, attendees will take classes in Charms, Potions, and Divination. This year’s school session also involves an escape challenge – Dolores Umbridge has been known to lock an entire class out of the Hogwarts building and onto the Hogwarts grounds. It will be up to each class to work together to solve the clues and find the magic key that opens the door back into Hogwarts proper! And, of course, no one will leave without their wand from Ollivander’s Wand Shop personally matched by Ollivander.

These sessions are drop-off only, with Prefects escorting the children through their 2 hours of classes. Admission is $30 per child. Costumes are encouraged. Also available for purchase: Class T-Shirts (long sleeved), $20 each, and School Portraits, $10 each. Questions? Click here for FAQs.

For children ages 6 and up.

Do you know the perfect line from a Harry Potter book that you’d like to see on a t-shirt? Submit a caption for our T-Shirt Caption contest – if selected, your chosen caption will appear on this year’s souvenir T-shirt. You’ll receive a T-shirt and 2 tickets to a session of your choice! Entries should be fun, not too lengthy, and have instant book recognition. Past year’s captions have included, “I solemnly swear that I am up to no good,” and “I don’t go looking for trouble. Trouble usually finds me.” T-shirts are available for pre-order online, and during the event. Supplies are limited, pre-ordering is suggested to ensure you get the size you want.

Submit your T-Shirt Caption entry to blackstonehalloween@gmail.com, and be sure to include your name, age, town, phone number, and email address. Entries must be submitted by August 31. Winner will be chosen by Hogwarts faculty and announced in September. By entering the contest, you agree that your name and image may be used in promotional materials for James Blackstone Memorial Library and A Hogwarts Halloween at Blackstone. Hogwarts is part of the Harry Potter universe created by J.K. Rowling.

We anticipate a sold-out crowd of 400 children, who will all receive souvenir program books to take home to their families, each with your sponsor logos inside. Event posters with your logo will be hung in the library leading up to the event, so all of the daily visitors to the Blackstone (an average of over 500 per day) will see your support for the library and this magical weekend. Your logo will also be displayed on our website, with links to your website, and will be shared in emails and social media posts leading up to the event, reaching thousands of members of the local community. See the complete Sponsor Information Packet here (PDF).

Proceeds from A Hogwarts Halloween will benefit the Blackstone Library, a 501(c)(3) nonprofit organization.
