Rarezas de colección: An Exhibition of Telefónica's Technological Heritage at Espacio Fundación Telefónica

This exhibition showcases 'collection rarities' from Telefónica's Technological Heritage, presenting unusual and diverse objects beyond typical switchboards and telephones. It highlights the specialized work involved in telecommunications and the history of technology.

The exhibition 'Rarezas de colección' (Collection Rarities) aims to bring to light the lesser-known but essential pieces within Telefónica's Technological Heritage. These are not just the common switchboards or telephones but hundreds of diverse items with varied functionalities, some even difficult to identify within the telecommunications domain. The display features these peculiar and sometimes aesthetically striking objects to illustrate the significant human effort and specialized labor involved in establishing and improving telephone communication over decades. Beyond the objects themselves, the exhibition also serves as a reflection on the importance of preserving and documenting history, emphasizing the role of the Laboratorio General de Ensayos (General Testing Laboratory), established in 1926. This laboratory was crucial for verifying the quality of materials used in the company's work. The exhibition showcases pieces analyzed by this lab, such as rheostats and microscopes used for electrical and material testing, as well as equipment like carbide lamps and candlestick holders used by 'Empalmadores' (jointers) and 'Celadores de Telefónica' (Telephone Watchmen). It delves into the training and strict requirements for these roles, underscoring the commitment to communication secrecy and the company's early focus on standardization and a corporate culture.

The exhibition is open from Monday to Friday from 10:00 to 20:00, and on Saturdays, Sundays, and holidays from 11:00 to 20:00. Admission information is not explicitly detailed but is implied to be part of the general museum access.
