Ponce is both a city and a munic­i­pal­i­ty in south­ern part of Puer­to Rico. The city is the seat of the munic­i­pal gov­ern­ment. The City of Ponce is the sec­ond largest city in Puer­to Rico out­side of the San Juan met­ro­pol­i­tan area, and is named after Juan Ponce de Leon y Loayza, the great-grand­son of Span­ish con­quis­ta­dor Juan Ponce de Leon. Ponce is often referred to as La Per­la del Sur (The Pearl of the South), La Ciu­dad Seño­r­i­al (The Noble City), and La Ciu­dad de las Quenepas (Genip City). The city of Ponce serves as the gov­ern­men­tal seat of the autonomous munic­i­pal­i­ty as well as the region­al hub for var­i­ous Gov­ern­ment of Puer­to Rico enti­ties, such as the Judi­cia­ry of Puer­to Rico. It is also the region­al cen­ter for var­i­ous oth­er Com­mon­wealth and fed­er­al gov­ern­ment agen­cies. The city is also the seat of a Catholic Dio­ceis.  The Munic­i­pal­i­ty of Ponce, offi­cial­ly the Autonomous Munic­i­pal­i­ty of Ponce, is locat­ed in the South­ern Coastal Plain region of the island, south of Adjun­tas, Utu­a­do and Jayuya; east of Penue­las; west of Jua­na Diaz; and bor­dered on the south by the Caribbean Sea.  The region of what is now Ponce belonged to the Taino Guay­nia region, which stretched along the south­ern coast of Puer­to Rico. The region was led by cacique Aguey­bana. He was one of the caciques that greet­ed Span­ish con­quis­ta­dor Juan Ponce de Leon when he came to the island in 1508.
The coat of arms of Ponce con­tains a red and black coloured shield. There is a five tow­er gold crown that indi­cates that Ponce is a city by roy­al decree. As an exte­ri­or frame to shield, there is a sug­ar­cane plant on the right of the shield, and to the left a cof­fee tree branch. The shield of Ponce is divid­ed by a diag­o­nal line that cross­es straight from the supe­ri­or end to the left infe­ri­or end. In this divid­ed field is the col­or red (for the fire that almost destroyed the city), that cov­ers the supe­ri­or right por­tion and the col­or black (for the ash­es after that fire). On that black and red back­ground is a yel­low lion with black mane, walk­ing towards the left of the shield, fac­ing right of the shield. The lion is on a bridge, mean­ing that you must cross a riv­er to enter the city by any region. The shield is bor­dered by a cof­fee plant branch and a sug­ar cane plant, in which the ear­ly econ­o­my of the city was based.
