I really did! On Google maps first and I was like 'Why I didn't know that there is a medieval castle so closed to Glasgow! And I've never seen it!'
Then I took my bike and and using the 75 cycle route most of the time I went to see the castle.
And there it was, set on the river bank. Apparently Bothwell is Scotland's largest and finest 13th century castle! Not much to see, to be honest, but I liked walking along the walls trying to imagine life there centuries ago.
It was very peaceful place, almost no one there. And there was a very friendly custodian who told me a little bit abut the history.
