Di and Chris Bell


Chris and Di 
We are Chris and Di Bell and we live in an old cottage in rural West Wales. Welcome to our little website!

Chris is a retired engineer who used to make special bits for cycles (see below). Di is a retired social worker who enjoys gardening and looks after Chris.

Our daughter Sandra lives in Bristol with our 4 grandchildren Craig, Alesha, Cayla and Mason.

We met in the 1970s in the beautiful country of Lesotho where we were volunteer teachers. Our African experiences have influeneced us for the rest of our lives.

Nowadays we enjoy welcoming friends and visitors from all corners of the World through the Servas peace host organisation.

If you need to find us, here's a map.
