Tower Level 1 - Help

Ok, so I'm at Tower Level 1 in the second town. There are two areas with holes, one blinking one none blinking. I know I have to find a switch somewhere to close the none blinking holes, but I can't find it. I found a site that said its in a pit somewhere but I still not having any luck. Anyone remember where this is? Thx

Nvr mind I found them hiding behind pillars also found two other secrets while I was looking
