The Rover-Landers of BC

I got under my Disco 1 today to locate the A/C drain holes and unplug them. (I read online that they were 'easy to find'. I disagree, but finally accomplished the mission. :alien: )

However, while under the car, I did notice three holes (one quite large) on the bottom of the car. (Photos are attached.) These holes come up just in front of the driver's seat.

So, why are there holes in my car? :shock: As a temporary fix, I put duct tape over them.

As always, advice appreciated. Thanks in advance.

They look like drains. I know the floors in Land Rovers are higher in the center of the vehicle so water can drain out the doors but maybe those are just extra drainage holes.

I wouldn't worry about it.
