The Museu de la Guàrdia Urbana was officially opened on 10 October 2002. Located on the ground floor of the Headquarters building, C/ Guàrdia Urbana, nº 3, in the Sants-Montjuïc district, it features important collections of items relating above all to the Guàrdia Urbana de Barcelona, as well as other police forces, as a result of exchanges carried out on visits to Barcelona made by the various forces.

It is currently showing several displays of the various uniforms that have been used during the GUB's 175-year history, from the first model of clothing used in 1843 to the latest from 2017, and by the Mounted Unit Section of 1856, 1968, full and ceremonial dress (according to the representative protocol); uniforms from the motorised section from the 1960s and 2000s; entire uniform and equipment of a night watchman from the 1950s, as well as other important outfits from the GUB's historical development.

Historical vehicles displayed include a Harley motorcycle from 1929, the first vehicle used by officers to mark the 1929 Barcelona International Exposition, a 250 cc Sanglas motorcycle with a 1953 licence plate and, closing the circle, a Honda Paneuropean from 2007.

It has an extremely important documentary collection featuring all the GUB’s identity card templates from the 1920s to the present day, as well as administrative documents stretching back to over half a century.

Meanwhile, the photography collection derived from the Arxiu Històric de la Ciutat and individual donations from family members of former GUP officers provide us with pictures ranging from the early 1900s to the present day which show the development of the uniforms and the various types of work that the GUB had to carry out over time.

Finally, we can find collections of small items making up the museum's sentimental collection. These displays invite visitors to reflect on the human need to preserve records while keeping memories alive through their evocative power connecting the present with the past.
