This is a male of the longhorn beetle Megopis scabricornis, 22-56 mm long. This one was about 50mm long. It is a wood boring beetle.
Thanks must go to Frank Köhler for help with identification. www.koleopterologie.de is a great resource.
I have found the following information for your interest from http://www.forestpests.org/hungary/longhornmsc.html.

South-western palaearctic species. In Hungary this species is typically associated with old floodplain forests, parks, graveyards and established trees lining roads. Food plants include a range of broad-leaved trees, particularly willow (Salix) and poplar (Populus). This is one of the few species able to develop in black locust (Robinia pseudoacacia). The larvae develop for 3-4 years in dead wood in injured or dying stems. Several generations may develop in a single stem. Before pupating the larvae open an emergence hole through which the adults leave after several weeks in the pupal stage. The adults fly at night from early July until early August, spending the day in bark crevices and similar places. Mating and oviposition occur on the stem either in hollows or on wounds. Dead adults can be found at the base of the host plant as in Lucanus cervus and Oryctes nasicornis.

I took the photograph of this beetle in the evening as it was resting on the patio at a friend's house. I hope it just bores into trees and not houses.

Hello Morag,
Great post, very interesting. I guess if a house is made of wood then it's fair game for this little fellow. Nice detail in the shot and excellent exposure and colours. I thought initially that the leaves at the bottom were distracting, but the more I look the more I think they add a good splash of texture and colour to the image. Well executed image and a good informational note, great work.
Regards,
Adrian
