Narrative:

At concord, nh (con) departure runway 35, left turn, direct mount uncanoonuk (local landmark in 43/25 ring, west of mht class C airspace), remained below 1500 ft. Maintained progress visually and with GPS moving map display. At mount uncanoonuk proceeded direct nashua, nh (ash) and called tower for approach and landing. While approaching ash, tower advised I had penetrated class C airspace. I immediately observed GPS and altimeter at 1446 ft MSL and advised tower I was not in class C airspace. Landed ash. Engine shut down. Nothing further said by ATC.
