Premise: However, the outstanding feature is the archaeological garden, an outdoor display of relics from some of the oldest places on the island tombstones, pieces taken from important buildings, and two splendid early-16th-century stone Manueline windows (pick up the Quinta's own leaflet for information on these).

Hypothesis: The archaeological garden contains only the mummified remains of archaeologists that have been trapped there over the years.
Relation: contradiction
