The centre is built on the site of the Royal Naval Hospital Bighi, which operated from 1832 until 1970.
The planetarium uses a digital projection system to simulate the night sky and space exploration.
The site includes a 'Villa Bighi' historical trail detailing the buildings' former medical use for British naval personnel.
Esplora is a member of the European Network of Science Centres and Museums (ECSITE).
The outdoor area features a 'Musical Garden' where science principles are demonstrated through sound-based installations.
Esplora Interactive Science Centre is housed within the historic Villa Bighi, a former Royal Naval Hospital overlooking the Grand Harbour in Kalkara. The complex features hundreds of hands-on exhibits across indoor and outdoor spaces designed to engage visitors with physics, biology, and chemistry. It includes a dedicated planetarium showcasing astronomical content using advanced projection technology. The site preserves significant 19th-century military architecture while integrating modern scientific installations. Visitors can access specialized zones such as the 'Life at Sea' exhibition and dedicated play areas for younger children. The centre serves as a hub for STEM education in Malta, frequently hosting workshops and demonstrations. Its hillside location provides elevated views of the Valletta coastline.
