I am not a fan of the tourist type photos but St Paul’s Cathedral has always been among my favourite places in London.
I used to get off at St Paul’s station on the Central Line in order to get to Southbank. I always enjoyed taking that route as it was always a good excuse to stand outside this magnificient Cathedral and admire its architecture . I would usually then walk around and take photos from every corner and angle.
I find that Autumn is always the right time of the year to take nice photos there.
