'Tilia Courtyard', in the old town of Zurich, Switzerland, is the historical site of a Roman castle, and the later Carolingian Kaiserpfalz.

[1] In 1747, a second-century Roman tombstone was discovered at the site, bearing the oldest attestation of Turīcum, the Roman-era name of Zurich, as STA[tio] TURIC[ensis], at the time a tax-collection point.

In the early 21st century, it serves as a recreational space, a green oasis, and automobile-free zone in the old historic city centre.

Its elevated position makes it a popular location for tourists to get an overview of the geography of old Zurich.

In April, during the local holiday of Sechseläuten, the Lindenhof serves as the base of operations for whichever is the "guest canton" for that year.
