Puerto Vallarta is the second largest urban agglomeration in the state after the Guadalajara Metropolitan Area. The City of Puerto Vallarta is the government seat of the Municipality of Puerto Vallarta, which comprises the city as well as population centers outside of the city extending from Boca de Tomatlán to the Nayarit border (the Ameca River). The city is located at 20°40′N 105°16′W / 20.667°N 105.267°W / 20.667; -105.267. The municipality has an area of 681 square kilometres (262.9 sq mi). To the north, it borders the southwest of the state of Nayarit. To the east, it borders the municipality of Mascota and San Sebastián del Oeste, and to the south, it borders the municipalities of Talpa de Allende and Cabo Corrientes.[4] Puerto Vallarta is named after Ignacio Vallarta, a former governor of Jalisco. In Spanish, Puerto Vallarta is frequently shortened to "Vallarta", while English speakers call the city P.V. for short. In Internet shorthand, the city is often referred to as PVR, after the International Air Transport Association airport code for its Gustavo Diaz Ordaz International Airport. In the 16th century, Hernán Cortés explored the Pacific side of Mexico by ship. Cortés used the established port of Acapulco to resupply and anchor his ships along the journey. During the early 1500s, he sent two of his ships North to explore the coastline without him. One of his ships wrecked in Banderas Bay and all but three men were reportedly killed. It is believed the corpses of the lost sailors washed ashore. Native villagers encountered numerous corpses on the beach for days after the wreck.[5]
