Vines have thrived on the southern slope of Strahov for centuries. There were even royal vineyards here during the reigns of Wenceslas IV and Vladislaus II of Hungary. The earliest historically documented landowner to grow vines on this sunny slope was Jan Theodor Sixt of Ottersdorf in the first quarter of the 17th century. The Francisco Josephinum Institute for the Care of the Blind was built here 130 years ago, and a large English-style park was gradually laid out around the house. Part of the 890 m² plot on the eastern and northern side of the grounds was reclaimed in 2017, and 475 vine seedlings were planted. Every year, the vineyard hosts the annual harvest of the Solaris grape variety, which has an excellent sugar content of over 21°. In addition to Solaris, it also grows three varieties of table grapes - Prim, Rosana and Muscat Blue. Besides the gardeners, the vineyard is also tended by volunteers who come to the Palata Home.
