The region of what is now Cidra belonged to the
Taíno region of Cubuy, which covered a portion of the center of Puerto Rico. The region was led by cacique
Caguax. There are not many records that show that the region was populated after the
Spanish colonization. However, it is believed that around 1795, a
Catalan named Frujols built a
hermitage or shrine around which a small village settled. The settlement became a ward of
Cayey, until 1807 when the residents gave the power to Victoriano de Rivera to ask the Governor for permission to found an independent town. In 1809, a landowner known as Bibiana Vázquez donated the land needed for the foundation, and Governor
Salvador Meléndez approved the petition. Victoriano de Rivera was appointed to lead the town, but he was quickly replaced by Wenceslao Vázquez due to illness. At the time of its foundation, Cidra had 26 houses and 11 huts. It is believed that its name is derived from the
citron fruit which was widely cultivated in the region. During the years following its foundation, a church and city hall were built. By 1822, there were already two public schools in town. Two years later, a road communicating the town with
Caguas was opened. In 1868, the population of Cidra was more than 5,000 residents, which included European immigrants and slaves. Puerto Rico was ceded by
Spain in the aftermath of the
Spanish–American War under the terms of the
Treaty of Paris of 1898 and became a territory of the United States. In 1899, the United States conducted its first
census of Puerto Rico finding that the population of Cidra was 7,552. In 1902, the
Legislative Assembly of Puerto Rico approved a law for the consolidation of certain municipalities. As a result, Cidra was again incorporated to the town of
Cayey. However, in 1905 a new law revoked the previous one, turning Cidra into an independent municipality again.
Hurricane Maria A category 5, and high-end category 4
Hurricane Maria when it hit Puerto Rico, on September 20, 2017 triggered numerous landslides in Cidra. A week before
Hurricane Irma, another category 5 had passed over Puerto Rico causing some damage. With Hurricane María, some areas of Cidra experienced more than 25 landslides per kilometer. Citizens, with machetes in hand, worked to clear the roadways of debri after the hurricane hit, especially in
Rabanal,
Arena and
Ceiba, barrios of Cidra located at high altitudes. 1500 homes were left without a roof and many would never receive funds for repairs. One local (analog) radio antenna survived the catastrophe allowing for some communication within the town to take place. Before the hurricane there had been plans to eliminate the radio tower, but when 92.7% of Puerto Rico's towers were destroyed by the hurricane, plans to eliminate the analog radio tower were scrapped.
Puerto Rico Highway 172, the main highway into Cidra from the
San Juan area had to remain closed for repairs for five months. It was not until six months after the hurricane struck that power was restored to Cidra. ==Geography==
