Problem: Guam:

The Chamorros, Guam's indigenous people, settled the island approximately 4,000 years ago. Portuguese explorer Ferdinand Magellan was the first European to visit the island on March 6, 1521. Guam was colonized in 1668 with settlers, like Diego Luis de San Vitores, a Catholic missionary. Between the 1500s and the 1700s, Guam was an important stopover for the Spanish Manila Galleons. During the SpanishAmerican War, the United States captured Guam on June 21, 1898. Under the Treaty of Paris, Spain ceded Guam to the United States on December 10, 1898. Guam is amongst the seventeen Non-Self-Governing Territories of the United Nations.

Problem: As a result of the Libyan Civil War, the United Nations enacted United Nations Security Council Resolution 1973, which imposed a no-fly zone over Libya, and the protection of civilians from the forces of Muammar Gaddafi. The United States, along with Britain, France and several other nations, committed a coalition force against Gaddafi's forces. On 19 March, the first U.S. action was taken when 114 Tomahawk missiles launched by US and UK warships destroyed shoreline air defenses of the Gaddafi regime. The U.S. continued to play a major role in Operation Unified Protector, the NATO-directed mission that eventually incorporated all of the military coalition's actions in the theater. Throughout the conflict however, the U.S. maintained it was playing a supporting role only and was following the UN mandate to protect civilians, while the real conflict was between Gaddafi's loyalists and Libyan rebels fighting to depose him. During the conflict, American drones were also deployed.
What is the name of the Libyan leader opposed by UK forces?

Context and question: The public water supply network was completed in 1850, and in 1858 the architects Sebastian Monleon Estelles, 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?
