The Miller's Monster Mash Bash

A cartoon image of the museum and some halloween pumpkins

Step back in time for a spine-tingling adventure this Halloween at Mill Green Museum & Watermill.

This year, our grounds are being overtaken by iconic creatures of yesteryear for a Monster Mash Bash!

From the carnivorous garden the murky depths of the mill race, come face-to-face with the Monster Miller and explore a haunted trail filled with classic scares and retro thrills.

Whether you're hunting for the perfect pumpkin in our pumpkin patch or enjoying a potion from the Scaredy Cat Cafe, there’s nostalgic fun for every little ghoul and goblin.

Don’t forget to don your best old-school costume - think classic Dracula's, Mummies, and Wolfmen and join us for a day of good old-fashioned Halloween fun!
