Falco peregrinus - sighted April 2017

The Ayer Mill Clock Tower is the worlds largest mill clock. Its four big glass faces are only 6 inches smaller than Big Ben in London. It is the treasured icon and landmark of Lawrence, Massachusetts.The Ayer Mill, built to spin and dye yarn, was opened on October 3, 1910. Its grand, illuminated clock tower immediately became the architectural focal point of the Merrimack Valley.This is the best clocktower Ive ever seen in my life!

Really cool old mill.
