York, Tower 14 and Victorian buttress
The next tower along is close by a Victorian buttress put in place after large arch ways were inserted when the railway was pushed through the wall. Drawing the tower and buttress was a lesson in distinguishing the different dates of work. On the right the Victorian work uses regular sized and neatly cut blocks. These were done by machine. They are carefully graded in size from very small at the top to very large at the bottom. The older stonework is very irregular and has wide joints between the blocks.
