"Boca do Inferno" (Hell's Mouth) - Cascais - Portugal. It gets its name from the rough ocean waves which crash against the cliff face, forcing their way into a cave system, and spraying angrily from an opening above.
SPAIN - The Benedictine monastery of Santa Maria de Monserrat is built into the mountain and offers visitors a staggering view. Monserrat is translated 'sawed mountain'. It is about 45 km northwest of Barcelona.
