The Landmark Trust UK organization gives you a lot of options if you're craving a unique lodging experience. Founded as a building preservation charity by Sir John Smith and Lady Smith, the trust states that, “All landmarks are remarkable in some way for their architecture, history or setting.”
My favorite choices, though, are the literary offerings. Imagine spending a few nights in the Piazza S. Felice in Florence, Italy, which was the home of Robert and Elizabeth Browning. In Rome, the flat in the Keats-Shelley house flanking the Spanish Steps would be sufficient inspiration to have me pulling out my manuscript. And is there a wordsmith who could resist the inspiration to be found at the bucolic Tivoli retreat in Italy believed to have been owned by the poet Horace?
While the UK Landmark Trust has, by far, the greatest number of properties offering 180 accommodations in the Channel Islands, England, Italy, Scotland and Wales, other organizations offer choices in other countries.
