The oldest Catholic university that I know of is Georgetown, which was founded by the Jesuits in 1789. The next would be Mount Saint Mary's in Amortizable, Maryland, which was established by the Sulpicians as the seminary for the United States in 1808. There are any number of Jesuits institutions which were founded in the 19th century, with Spring Hill (1830) and Santa Clara (1831) being the oldest (not counting Georgetown).
To the best of my knowledge, the oldest Catholic educational Institution is Georgetown which was founded in 1789. Mount St. Mary's was founded shortly thereafter and graduated their first class in 1808.

There were dozens, if not hundreds of Catholic Churches in England, but they were all "appropriated" by the Church of England five hundred years ago. St Etheldreda's Church in London was built in the 13th century, and was purchased (!) back by the Catholic Church in 1873 so it is not only one of the oldest existed Catholic Churches, but it is still (or again) Catholic
