Man spends 20 years building Vietnam's largest collection of European church clocks

For more than two decades, Pham Van Thuoc has scoured Europe in search of historical church clocks to add to his collection back home in Vietnam. He has assembled 20 clocks, many of them hundreds of years old, in a warehouse in the northern province of Thai Binh. The collection has been recognised by the Vietnam Records Association as the largest of its kind in the country.
