Observatori de l'Ebre Historical milestone · Roquetes, Baix Ebre, Tarragona Founded in 1904 by the Jesuits Ricardo Cirera and Lluís Rodés to study the influence of solar activity on geophysical phenomena, it maintains solar, magnetic, ionospheric, seismic and meteorological sections and received the Creu de Sant Jordi in 1987. Today it is a university institute of the Universitat Ramon Llull, associated with the CSIC. It suffered severe damage during the Civil War and was rebuilt and expanded by its director, Antoni Romañà, between 1939 and 1970. Its buildings, spread through a wood, are included in the Inventory of Architectural Heritage of Catalonia; notable among them is the Landerer pavilion, of neoclassical style, with pseudo-Doric columns at the entrance portico. 1904 Photo: Josep Salvany i Blanch (Public domain) What to see and do in Roquetes
