I visited the hospital on the same day that I did with Johnsonville. Although we didn't get to go inside because of certain reasons that I will explain later, we did get some amazing pictures of the outside.
If you would like directions the hospital is in Newington, CT on Russell Road just off the Berlin Turnpike. Remember enter at your own risk, stay safe and respect authority.
The reason we did not get to go inside is because while we were taking pictures, a police car rolled up beside us and the police man inside asked us what we were up to. We told him we were only taking pictures and in no way were going to deface any of the property. He understood and was very lenient about what we were doing. He proceeded to tell us that the hospital had recently been broken into by an unknown person and had been robbed of its copper piping. There were a lot of people looking into the story and he was just watching the property to protect it. He very nicely told us that he would've loved to let us in and give us a tour, but wasn't allowed to because of the recent robbery.
Here are the only pictures I could capture of the place.
