Not sure where you are in the world, 002 cents. I take a week's retreat most years at Samyeling Tibetan Buddhist Centre in the Scottish Lowlands. It is more than just a temple complex, it is a community and very peaceful. It is on an old country estate which was gifted sometime back and then everyone took a part of building it up. I actually painted a small bit of the temple !
Have a look
