Nautical Brass Porthole

Check out this beautiful Authentic Ship’s Two Dog Brass Porthole – 20 Inch – Unbalanced Inset! What really makes this porthole stand out is that the inset (the part of the porthole that will sit inside of the wall when mounted) is unbalanced. Check photo #2 to see what I mean! It must’ve been custom made to be installed in a certain area of the ship. The dimensions are listed below.

The glass has a few marks from years of sea travel with minor pitting on the back side of the glass. If you don’t like the authentic glass markings, you could choose to have a mirror installed! Both dogs spin on and off with no issues. Its hinged window opens freely.


Glass Diameter: 14″
Porthole Frame Diameter: 20″
When Mounted, Porthole Extends Out: 7.25″
Weight: 65 lbs.

This porthole has an inset on the back, which will sit inside of the wall, allowing the porthole to display on the wall with bolts keeping it fastened. The inset measures 1.1 and 1.8″ in depth and 15.75″ in diameter.

The word “porthole” has nothing to with its location on the port side of a ship, but originated thanks to Henry VII of England in 1485. The king demanded on mounting guns that were too large for his ships and French shipbuilder, James Baker was brought on to solve the problem. He pierced the ship’s side so that the cannon can could be mounted inside. When there was heavy weather or the cannons were not in use, the openings in the ships were fitted with covers that latched tightly. These were called porte, which means door in French. Porte became port thanks to the English and eventually any opening on a ship was called a porthole.
