A manhole cover in Beaverton, Oregon, a few blocks from the main Nike campus. No leaves--the sidewalk sweeper must've been a bit ahead of me...

A really small one (10 cm diameter).

Almost invariably they paint arrows across them (e.g your photo, Ashlandish). I understand it as a way to mark the direction for opening, or the prying open point, or the direction of water flow, when not evident on manhole itself.

Since evolution has given us TWO ears and ONE mouth, we are supposed (me included) to be doing more listening than talking.

Wind-decorated manhole

A pomegranate plant was losing its flowers, wind carried them a short distance and they were captured by the edges of the manhole...

Optical Manhole

From the major Electrical Company in Italy, ENEL. Very nice fisheye effect...

A nice square one...

The hole underneath is round I guess. Otherwise the lid can fall down.

Round and Elliptical

Since the diagonal is 1.4142x the sides, it would be very easy to drop the lid inside the hole. I suspect there's a hinge (see center top) to prevent such an instance. You lift it from the opposite side (see lower L and R)

Two smaller ones, one round and the other elliptical. They are used by the Fire Brigade.

PS: I always come back to this thread because I cannot help to have a pornographic association with the subject line...

Please note the effects of the May 2012 earthquake (broken marble slates)

Entrance to a WWII bunker in La Línea de La Concepción. If I´m not mistaken it was a german project to have defenses against Gibraltar. This zone was very interesting at the time with many spies, crossing point from and to the mediterranean and from and to Africa-Europe connection.

Eureka Springs, Arkansas.  From 2014 when I used a Canon 50D and a 17-40 Canon lens.
