I went to Llanerchaeron, a Welsh estate/museum now owned by the National Trust last week.
It's an old medieval/renaissance estate, that was refurbished and redesigned by John Nash, the architect who designed most of Buckingham Palace.
I also go to a museum in Carmarthen, the county town of Carmarthenshire, in a few weeks.
And then to Newport, to see the Newport Ship, a 15th century ship uncovered in Newport by archaeologists, some of whom are professors from my university!
Last year I went to Hadrian's wall on a field trip, walked along part of the wall, and visited various Roman sites, such as Vindolanda, the Roman Army Museum, Housesteads Roman fort and Corbridge Roman town.
And then 3 years ago, with my college Classics class, we visited Rome for about 5 days.
We visited the Coloseum, Roman Forums, Pantheon, Vatican, Vatican museum, Ara Pacis, Baths of Caracalla, Spanish Steps, Trevi Fountain, Piazza Navona, Trajan's Column and Market, the Palatine (including Augustus' house), and the Capitoline Museum (the most amazing statue, the Dying Gaul is inside).
