Inaugurated in 1904, this Modernista observatory 415m above sea level on Tibidabo is still a functioning scientific foundation. On certain evenings visitors can observe the stars through its grand old telescope; check the website for schedules. Observations must be pre-booked; English-language visits are on Saturday nights.
From mid-June to mid-September, Sopars amb Estrelles offers an evening of high-end dining and astronomy here.
