[Grammar] "Built" or "Having been built"

[xxwzs]

Here come four sentences altogether in Group A and B:
Group A
1. This church was built in 1870 and it attracts many tourists now.
2. Built in 1870, this church attracts many tourists now.
Group B
3. Because this church was built in 1870, it attracts many tourists now.
4. Having been built in 1870, this church attracts many tourists now.
I would like to be told whether both sentences are correct in each group.
If so, do both sentences in each group express the same meaning?
Really appreciate your reply. Thanks.

All sentences are correct. With the exception of 3 which gives a reason why the church attracts many visitors, all the other ones mean pretty much the same thing.
