Pucallpa (Quechua: puka allpa, "red earth") is a city in eastern Peru located on the banks of the Ucayali River, a major tributary of the Amazon River. It is the capital of the Ucayali region, the Coronel Portillo Province and the Calleria District.Pucallpa was founded in the 1840s by Franciscan missionaries who settled several families of the Shipibo-Conibo ethnic group. For several decades it remained a small settlement as it was isolated from the rest of the country by the Amazon Rainforest and the Andes mountain range. From the 1880s through the 1920s a railway project to connect Pucallpa with the rest of the country via the Ferrocarril Central Andino was started and dropped several time until it was finally abandoned. Pucallpa's isolation finally ended in 1945 with the completion of a highway to Lima through Tingo Maria. The highway allowed the commercialization of regional products to the rest of the country, thus improving the economic outlook of the region and its capital, Pucallpa. However, the heavy rainfalls of the Amazon Rainforest remain a problem as they erode the highway and can even cut it by causing flash floods.Pucallpa is served by air through the Captain Rolden International Airport and by river through its port Pucallpillo near the center of the city. During the high water season, the floating ports of La Hoyada and Puerto Italia are used for riverine communications. Pucallpa is connected by road to Lima via the cities Huánuco and Cerro de Pasco.
