As a landscape subject lighthouses are very popular. You’ve got oceans, cliffs, colors, and the romance of sailors at sea in search of land.
There are many lighthouses and many facts to go with the construction, use, and history of lighthouses. Many of them have seen their day to be replaced with digital tones (fog horn) and strobe lights. Sailors have satellite navigation now so lighthouses have become historical relics.
The great thing about painting is that you can modify the period by adding old ships, buggies, or a fresh coat of paint to remind us of yesteryear.
