Ruskeala

Ruskeala is a settlement in the Republic of Karelia, Russia, located near the border with Finland. It is best known for the Ruskeala Mountain Park, a former marble quarry that has been transformed into a tourist attraction. The park features stunningly clear, emerald-green water filling the abandoned quarries, surrounded by steep marble cliffs.

The quarrying of marble in Ruskeala began in the 18th century and supplied material for prominent buildings in Saint Petersburg, including the Winter Palace and St. Isaac's Cathedral. Production ceased in the 20th century, and the quarries were gradually flooded.

Today, the Ruskeala Mountain Park offers a variety of activities for visitors. Boat tours allow exploration of the flooded quarries and their hidden grottoes. Hiking and walking trails wind through the park, offering scenic views of the marble formations and surrounding forests. The park also features a ski resort in winter, utilizing the natural terrain.

The area's geological history and the dramatic transformation from industrial site to natural park make Ruskeala a unique destination. The park is a popular spot for both domestic and international tourists interested in nature, history, and outdoor recreation.
