Port­land Head Light, locat­ed on Cape Eliz­a­beth in Maine, was first lit on Jan­u­ary 10, 1791, and decom­mis­sioned and auto­mat­ed on August 7, 1989. As such, it is one of the state’s old­est light­hous­es. The for­mer keep­ers’ quar­ters, built in 1891, have been con­vert­ed into a muse­um con­tain­ing light­house lens­es and inter­pre­ta­tive dis­plays. The tow­er is only open in Sep­tem­ber on Open Light­house Day when access is very lim­it­ed, but if you make it to the top, you’re sure to have a stun­ning view of Maine’s rocky coast­line and the Atlantic Ocean.
