We are very excited to introduce our “Seasonal Celebration by Starlight” event here at the OSC.
Come join us for our festive family event.
Explore our fully interactive exhibits and enjoy a bite to eat from our cafe Christmas menu. Why not try one of our Camembert & cranberry toasties followed by a glass of our delicious spicy mulled wine and a mince pie.
Come and meet Santa and his elf and take selfies.
This will be followed by a dance along to Christmas songs sung by our special guest star Mary Grace.
During this time, if weather is clear, there will be an opportunity to look through one of our historic telescopes.
A festive experience for all to enjoy!
We look forward to seeing you there!
