Everyone approaches these steps with caution! I have run up them many times but seldom down! When they are covered with fallen wet leaves it is almost impossible to remain upright! That of course is the best time to photograph them, so I will try again later in the year.
Any normal local authority would have covered them with warning signs or even forbidden access, but this is Machynlleth!! - pronounced, as nearly as I can get it without going into great phonetic detail, MAK UN KLETH. It's inhabitants are generally likley to take responsibility for their own actions and don't look to blame someone else when things go wrong!
