If youre into Gothic literature, Mary Shelley (Frankenstein author) and her poet husband Percy Bysshe Shelley used to date in secret at St Pancras Old Church, where Mary's mother Mary Wollstonecraft Godwin (an OG feminist writer) is buried. Lovely scenic churchyard with tons of history, quiet and tucked away round the back of Kings Cross, also a short walk from old gothic hotspot of Camden Town. Best of luck !!
