That reminds me of a story I heard. In Cleburne there was a hotel, the Greenbriar, that was across the street from the Courthouse on the square. It was a pretty grand back in the day. I heard that that there was an underground tunnel that led from the Courthouse to the hotel and that judges, lawyers and other folks used to go to the hotel and gamble. There was supposedly a lot of high stakes gambling at the hotel and that way the judges wouldn't have to be seen going there. Of course, judges stayed there and I am sure the tunnel was officially for the visiting judges to use on official business.
The Greenbriar turned into a flop house, but is being rennovated. They don't even have court at the Courthouse anymore. All the old Courthouses in Texas are being restored and no one uses them for anything but museums.
