What's this repeating area in the original Zelda?

I was playing the Switch virtual console edition of Zelda I, and I found some area near the bottom left of the overworld map. It looks like it's a plus-shaped walkway with Moblins and it seems to be going on forever.

I checked a map online, and my guess is when I leave the screen into the loading zone, it puts me back at the start of that room.

Is this an intended feature of the game, or is it a bug in the switch's virtual console?


Solution 1:

If it's the maze I'm thinking of, you need to go through it in a special order. North -> West -> South -> West
