Southport’s historic Hesketh Park Observatory is opening its doors to visitors this month as part of the annual Heritage Open Days festival across Sefton, 11 – 20 September 2026.
Located within the park grounds on Albert Road, the wooden observatory was first constructed in 1901. Inside, the building houses a six-inch aperture telescope built by manufacturer Thomas Cooke in 1869, which still retains its original clockwork drive system.
Visitors will be able to look inside the mid-Victorian structure and learn about the observatory’s role in local astronomical history. Entry to the observatory is completely free with no pre-booking required on the following dates and times:
Sunday 13 September: 11:00 – 16:00
Wednesday 16 September: 11:00 – 16:00
Sunday 20 September: 11:00 – 16:00

The opening is one of several free heritage events taking place across the borough this month. While many venues are drop-in, some guided walks and tours require booking in advance due to limited spaces.
