Your pictures: Arches

Ben Dixon: "There is something about things framed in threes which offers symmetry and balance. I like these three mini scenes all framed and brought into one - the subjects all appear impervious to each other's presence."

Richard Woods: "This is (or was) called London Bridge. (Sorry England, we keep borrowing your place names in Australia!) Sadly, since this photo was taken, this particular 'London Bridge' has fallen down and a somewhat less spectacular one a little to the left of this one has taken on the name. My friends and I are quite glad it held together while we were there at least. Didn't give it a thought at the time. Crazy youth."

Mark Davies: "Arches above the central assembly hall of the Bangladesh Assembly National Parliament Building, designed by Louis Kahn. Maintenance workers are in the process of repairing the marble strips set into the concrete."

Laura Danae Rubino: "I walked out of a coffee house in Sebastopol, California, looked up and caught this image of a solar halo."

John Watson: "Dusk at Whitby Abbey and the rays of light through the arches are like Dracula's fingers spreading over the unaware town."

Chloe Edwards: "The view from a taxi crossing Nhat Tan Bridge, Hanoi, Vietnam. The arches emerge not through the mist but the thick smog that fills the air in this city."

Claire Goodbody: "A photo taken whilst driving past the Twemlow Viaduct near Holmes Chapel in Cheshire. The viaduct carries the Manchester to Crewe railway over the River Dane."

Bill Reeds: "I was really pleased to find these arches which seemed tailor-made to frame the beauty of the Taj Mahal."

Manisha Malhotra: "This photo was taken near Marienplatz in Munich. I love clicking black and white silhouettes and got the opportunity to capture this one as people started moving out after the rain stopped."

Yogesh Patel: "Tortured by nature, but alive, Arches National Park, Utah, USA."

Brian Charles Lehrer: "Matching an outfit to the soft red, white and blue palette of Ananda Temple in Bagan, Myanmar."

Jenny Downing: "Droplets of overnight rain have settled on to a blade of grass, causing it to bend over in an arch."

Robert Wilson: "The last port of call for the Titanic, the town of Cobh (formerly Queenstown) is situated on the Great Island in Cork Harbour, Ireland. The only road in or out of the island is across Belvelly Bridge which is over 200 years old. As I live in Cobh, I travel over this bridge daily and an idea for this shot came to me one night during one of these trips. Ensuring that there was a very low tide, I was able to safely walk under the arches and light them up with a flash gun. Using a long exposure, this captured the three arches lit up and also captured me three times."

Daniel Furon: "The skeleton of an installation called the Ammonite."

Mike Hume: "Ribblehead Viaduct silhouetted at midnight by the light of a full moon, whilst a handful of stars twinkle above the glare of the full moon's indigo sky, Yorkshire Dales National Park."

Simon Tasker: "This dolphin creates a perfect arch whilst enjoying some time playing with its keeper at Dolphin Bay, Dubai, taken in summer last year."

Justin McAteer: "Collapsed Arches. An homage to Magritte's 'Ceci n'est pas une pipe' and a tribute to those who suffer from flat feet."
