Karasan, Regional cultural heritage site in Partenit, Russia.

Karasan is the Raevsky palace, built 1885–1887 by architect Karl Eschlimann in Moorish Revival style on the estate's old site. Its north facade has a projecting risalit with a portal and faceted columns, and the west facade a wooden balcony with slanted latticework modelled on the Bakhchisarai Khan's Palace. A faceted domed tower with a 16-window gallery stands on the east side; the sea-facing south facade has carved wooden balconies.

General Borozdin founded the estate in 1820 while working with directors from Nikita Botanical Garden and Saint Petersburg Botanical Garden to design its grounds. Since 1924, it has operated as a sanatorium and served as a medical facility.

The estate's name comes from the Crimean Tatar Qara Asan, after the Karasan family; a rival explanation links it to the Persian Khorasan, "east, sunrise". The west facade's wooden balcony with slanted latticework follows the Khan's Palace in Bakhchisarai, while the south park facade uses carved wooden balconies with arches and lace-like valances.

The property sits directly on the coast and is easily accessible in good weather. The large park allows for extended walks and exploration of its different zones.

The park's oldest feature is a grove of Italian pines (Pinus pinea) said to be the largest on the Black Sea coast; the plantings began in 1820 under gardener E. Yu. Libo, following advice from Nikita Botanical Garden director Nikolai Hartwiss and St Petersburg's Fyodor von Fischer.
