Consider how difficult to reach the place, it is not worth the trouble. Taxi ride to the other bank cost 175000 VND and the short crossing is 50000 VND On the way back, I had to call a taxi, it was like I had any bargaining power, that I paid 200000 VND WILLINGLY.
The temple is small, even going in the hall caused some comments from the "guardian". No photo allowed and some website says certain buildings are architecturally interesting. Perhaps only the main hall. All others are modern day concrete building, nothing special. You can find them in any street corners in Vietnam.
