Tivoli is about 20 kilometres from Rome, on the lower slopes of the Sabine Hills. Its finest ruin, the so-called Temple of Vesta (also known confusingly as the Temple of the Tiburtine Sibyl), is a circular building dating from the 1st century BC. Situated dramatically above a precipice and cascade, it has been admired by artists since the 16th century because of its picturesque location and it became a famous attraction for Grand Tourists. Wilson visited the town on several occasions.
