I hate to disappoint, but I'm answering the actual question today because it's one of my favorite architectuaral features, especially in Tudor, French Country & Irish Castle. It's the round part! These are my shots of The turret at Dromoland Castle in Ireland. We stayed in this 500+ year old castle for 3 nights and lived like royalty. Turret is Italian and means "little tower" (torretta).

Our current house has one; 1880's triple brick Victorian.

I believe it's where Rapunzel lived! 

That's where Sandy sits when she decides to take 'Potshots' at me.

that's common today when building mcmansions.... now your questions are getting easy....

a good vantage point.

Wasn't that Rapunzel's house? Love the photo Thomas J. Nelson, Realtor shared! Now THAT's a turret

That pointy round thing on the roofline?

Gun mount.

It appears you offered up an easy one for the class today.  

I think it's where you keep Rapunzel.

Tony and Suzanne Marriott, Associate Brokers Both Thomas J. Nelson, Realtor and Kenneth J. Jones have this one.

A small tower designed for defending a wall from infiltration! Not so popular anymore! The dust is still heavy on my book. Keep them coming!

It is a gun like part that sets on top of a tank...but for a house?

I got  this one :)

I love the photo posted by Thomas.

A good thing to have for defending your castle.

This is a very popular architectural element ta buyers like in my market. Some of the buyers call them witches hats.

It is a tower at the top of a building.  We lived in a Tudor-style home in CA with a second floor, and it had a round turret over the front door area - very beautiful Tony and Suzanne Marriott, Associate Brokers!

Isn't that the condition where you scream cuss words out of mid air and can't control your outbursts?  

You mean like a gun turret?  It rotates around.  I guess that would include a revolving restaurant, wouldn't it?  If that were the case, it should be called a Resturret.

It's the thing on the thing. 

It's where Rapunzel let down her hair.  

It's where my archers go to fight off the door knocking realtors!

Must be the owner of the syndrome ..

It's what the gun is attached to on the tank.  

Love these things - circular cylinder type of house extension.

Can also be done with windows giving added room to the interior. 

Thomas J. Nelson, Realtor  won with the great pictures.

That place where Rapunzel hung out.  Or at least her hair.  

That is what my grandsons think:

A way to walk around in small circles and view the sites.
