 The south transept 's southern wall is nearly complete , displaying the fine workmanship of the first phase . It shows the Gothic pointed arch style in the windows that first appeared in France in the mid @-@ 12th century and was apparent in England around 1170 , but hardly appeared in Scotland until the early 13th century . It also shows the round early Norman window design that continued to be used in Scotland during the entire Gothic period ( Fig . 6 ) . The windows and the quoins are of finely cut ashlar sandstone . A doorway in the south @-@ west portion of the wall has large mouldings and has a pointed oval window placed above it . Adjacent to the doorway are two lancet @-@ arched windows that are topped at the clerestory level with three round @-@ headed windows . The north transept has much less of its structure preserved , but much of what does remain , taken together with a study by John Slezer in 1693 , shows that it was similar to the south transept , except that the north transept had no external door and featured a stone turret containing a staircase .
