hangars

The plane at the back of the right row has a nose wheel, and most likely is a Friedrichshafen G.III bomber. The other planes are most likely LVG C.Vs.

I thought the thing in the back looked like a Voisin, left behind by the Russians.

Yeah, you're right--that plane has a rotary engine. Something made me think I was looking at a nacelle.

The de Havilland DH.82 Tiger Moth is a 1930s British biplane designed by Geoffrey de Havilland and built by the de Havilland Aircraft Company. It was operated by the Royal Air Force (RAF) and other operators as a primary trainer aircraft. In addition to the type's principal use for ab initio training, the Second World War had RAF Tiger Moths operating in other capacities, including maritime surveillance and defensive anti-invasion preparations; some aircraft were even outfitted to function as armed light bombers. The Tiger Moth remained in service with the RAF until it was replaced by the de Havilland Chipmunk during the early 1950s. Many of the military surplus aircraft subsequently entered into civilian operation. Many nations have used the Tiger Moth in both military and civilian applications, and it remains in widespread use as a recreational aircraft. It is still occasionally used as a primary training aircraft, particularly for those pilots wanting to gain experience before moving on to other tailwheel aircraft. Many Tiger Moths are now employed by companies offering trial lesson experiences. The de Havilland Moth club, founded in 1975, is now an owners' association offering a mutual club and technical support. Source: en.wikipedia.org/wiki/De_Havilland_Tiger_Moth

Thank you very much for that information!

Seems to be at 2 Fighting School RFC / RAF at Marske, UK. 1914-1918.invisionzone.com/forums/index.php?showtopic=66920

Is there anything that specifically identifies the location?

According to the reference I shared, going by the serial number visible on the rear fuselage, the aircraft was allocated to the School. It's not definitive, but unlikely to be wrong. Additional clues are the wooden buildings; implying a Home Establishment (UK) airfield rather than more temporary one with canvas hangars on the Continent. Also that it is with an Avro 504 behind (the rudder is distinctive) which was obsolete for front like work by the time the Dolphin entered service, but common on training airfields.
