I often notice doors when I travel, the color or size or ornamentation. Here are some I noticed while traveling around France on my Overseas Adventure Travel (O.A.T.) tour.
In Lyon, sometimes the door caught my eye, but more often it was the decorative work above the door that entranced me.
Red doors on churches often catch my eye. The one on the left is in Paris and the one on the right is in Bayeux.
Purple is my favorite color, so the doors to this church in Sarlat won my heart.
