Blackrock Castle Observatory

Overview

Blackrock Castle Observatory is a 16th-century fortified tower on the banks of the River Lee, 2 km east of the city centre. It has been reimagined as an interactive science centre and observatory run in partnership with University College Cork.

Highlights

• Cosmos at the Castle: Interactive science exhibition exploring the universe, with hands-on stations for all ages.
• Castle tower: The restored Elizabethan-era tower with river views from the battlements.

History

The original castle was built in the 1580s as a harbour watchtower. It burned down twice and was rebuilt in the 1820s in its current form. In 2007 it reopened as a science centre focusing on astronomy and space science.
