The public water supply network was completed in 1850, and in 1858 the architects Sebastián Monleón Estellés, Antonino Sancho, and Timoteo Calvo drafted a general expansion project for the city that included demolishing its ancient walls (a second version was printed in 1868). Neither proposed project received final approval, but they did serve as a guide, though not closely followed, for future growth. By 1860 the municipality had 140,416 inhabitants, and beginning in 1866 the ancient city walls were almost entirely demolished to facilitate urban expansion. Electricity was introduced to Valencia in 1882.
What was knocked down in 1866?
city walls

During the second half of the 19th century the bourgeoisie encouraged the development of the city and its environs; land-owners were enriched by the introduction of the orange crop and the expansion of vineyards and other crops,. This economic boom corresponded with a revival of local traditions and of the Valencian language, which had been ruthlessly suppressed from the time of Philip V. Around 1870, the Valencian Renaissance, a movement committed to the revival of the Valencian language and traditions, began to gain ascendancy. In its early stages the movement inclined to the romanticism of the poet Teodor Llorente, and resisted the more assertive remonstrances of Constantine Llombart, founder of the still extant cultural society, Lo Rat Penat, which is dedicated to the promotion and dissemination of the Valencian language and culture.
What group still exists and promotes Valencian culture?

The firm continued to pressure Kelsey and the agency to approve the application—until November 1961, when the drug was pulled off the German market because of its association with grave congenital abnormalities. Several thousand newborns in Europe and elsewhere suffered the teratogenic effects of thalidomide. Though the drug was never approved in the USA, the firm distributed Kevadon to over 1,000 physicians there under the guise of investigational use. Over 20,000 Americans received thalidomide in this "study," including 624 pregnant patients, and about 17 known newborns suffered the effects of the drug.[citation needed]
