La Vall d'Uixó, Cave system in Plana Baixa, Spain.

La Vall d'Uixó is a municipality in the Plana Baixa plain, situated about 25 kilometers south of Castellón and 8 kilometers from the Mediterranean Sea at an elevation of 118 meters. The location is characterized by natural cave systems, particularly the Sant Josep cave with an underground river, alongside residential and commercial areas with both historic and modern buildings.

Human settlements at Sant Josep cave date back approximately 16,000 years, showing how long this land has been inhabited. Later, Iberian and Roman civilizations established communities here, shaping the region's development across centuries.

The town displays a blend of Christian and Muslim influences through its architecture with chapels, towers, and a municipal market hosting contemporary art exhibitions. Visitors can observe these layered cultural traditions in everyday spaces where different heritage lines meet.

The Sant Josep cave features Europe's longest underground river system, accessible through boat tours and scheduled performances throughout the year. Visitors should prepare for damp conditions and wear suitable footwear when exploring the underground passages.

The Línea XYZ defense structures from 1938 feature preserved trenches that extend through mountainous terrain from Cuenca to Almenara. These military remains reveal engineering work from a pivotal period and can be discovered during walks through the landscape.
