About Biblioteca Pública Arús
Biblioteca Pública Arús was established by the will of Rossend Arús i Arderiu, a 19th-century Catalan playwright, journalist and committed freemason, who left his personal library and fortune on his death in 1891 to found a free public library for workers, explicitly conceived as a tool of popular education and social progress rather than a conventional civic or academic collection — a distinctly political, reformist origin that still shapes the library's identity today.
The building, opened in 1895 on Passeig de Sant Joan, reflects that founding spirit in its specialised holdings: it houses one of Europe's most significant collections on the history of freemasonry, alongside substantial archives on anarchism, the labour movement and other 19th- and early 20th-century social and political currents that more mainstream civic libraries of the era tended to avoid collecting.

More unexpectedly, the library has also built a genuinely notable Sherlock Holmes collection, a quirky but deliberate specialisation unconnected to Arús's original founding themes, said to be among the largest Holmes-related archives in continental Europe — a detail that regularly surprises visitors expecting only freemasonry and labour-history material.
Like the Ateneu Barcelonès, general public access runs through scheduled guided tours (seasonally, typically Saturdays in spring and autumn) rather than open walk-in browsing, and its ornate original reading room and exhibition spaces make the limited-access tour genuinely worth planning around if the subject matter interests you.
