Grotto

A grotto is a natural or artificial cave, typically small, shallow, and featuring a wide entrance. Natural grottos often form through water erosion in rock outcrops such as limestone or sandstone. Artificial grottos have historically been constructed in landscape gardens and estates as decorative architectural features, romantic retreats, or cool shaded spaces, frequently embellished with rockwork, shells, and water features or fountains.

• Natural grottos: Shallow caves found along riverbanks, rocky cliffs, or sea coasts formed by wave or current action.

• Architectural and garden grottos: Ornamental structures in classical and baroque garden design created to mimic natural caverns and add a sense of mystery to the landscape.
