Come back!
I am an expat living in California.
I've visited this museum several times over the last 50 years and always enjoy the buildings & well kept grounds.
The Unitarian chapel is a special place.
The museum has expanded over the years, there's much to see & nostalgia for me.
I was gratified on my last visit to find admission is free. It is well worth a visit especially for foreign visitors who are often not aware that Wales is a separate country with it's own traditions.
