Giardino Botanico Litoraneo di Porto Caleri
The Giardino Botanico Litoraneo di Porto Caleri (nearly 23 hectares), also known as the Giardino Botanico Litoraneo del Veneto, is a nature preserve and botanical garden located on  Via Porto Caleri, Rosolina Mare, Rosolina, Province of Rovigo, Veneto, Italy. It is open several days a week in the warmer months.

The garden was established in 1990, and operated by the Servizio Forestale Regionale di Padova e Rovigo in collaboration with the University of Padua. It consists of a thin strip of sand dunes between the mouth of the river Adige and the Po di Levante, containing indigenous vegetation of loose sand, salt marsh, and pine and elm forests. All told, it contains a dozen ecosystems with about 220 plant species, including native orchids. Three footpaths (600 meters, 1650 meters, and 2850 meters in length) allow close observation of the environment.
