Eight per cent shut their doors for good during the decade covered, the Church in Wales statistics show. The decline leaves 1,319 Anglican churches in Wales still open.
The Church said one way of tackling the long-term decline has been to encourage congregations to work more closely together.
Head of property, Alex Glanville was quoted by the BBC as saying: "We're grouping a lot more parishes and congregations together, about ten-15 churches in an area, and thinking which ones can we sustain."
The Church in Wales says the loss of congregations is a "significant issue" and, while the rate of churches being put up for sale has been steady, it is unlikely to slowdown.
According to the National Churches Trust, the rate of church closures in Wales is relatively higher than in England which differences in population size are taken into consideration. It is believed 20 Anglican churches are closing in England annually.
In a recent survey, it concluded attracting new worshippers amid falling attendance was the biggest issue facing Welsh churches. The Trust said offering new facilities was crucial in helping reverse the trend.
Head of communications, Eddie Tulasiewicz told the BBC: "The thing is to think about what can be done with these buildings over and above their religious purpose. They can hold meetings; concerts can take place.
"The other thing is history and tourism. A lot of churches and chapels are exceedingly beautiful and people do want to visit them."
