On their website it said there was 7pm open. We arrived at 5.40pm and the guy told us they were open until 7pm. But at 6.10pm, the exhibition at 3 and then at 6.15pm, the Closed6 building was all turned off by them. We were forced to go at 6.17pm and we were disappointed. If you want to be at 6, then make your time very close to 6Closing. But don't tell others you are open to 7, then make them feel unaffected and close when visiting Lights! That said, each room has six architectural art works, a small cafe, and even a library, very beautiful (we only saw the 3rd floor because they closed early and we had to go out). The ground is well maintained and there are lots of green plants. It was raining and when we went there were big snails on the ground. Echoes of prayer in this place. It was beautiful.
