Architecture

Let the games begin! Empty or filled, Berlin's historic Olympiastadion is a sight to behold

Edinburgh’s ‘skyline’ – with its castle in the background – seen from Calton Hill on a late winter afternoon

The television tower is one of the city's well-known landmarks

Caernarfon Castle, ‘guarded’ by dozens of small boats

The medieval town shows (almost) no traces of modern times

A painted façade and fire escapes in Orchard Road

Storm above the town

Buildings throwing some geometric shapes

Norman Foster's dome seen through crackled glass

Not as static as you'd think:  evening traffic whizzes past the Wiener Staatsoper

This wall shows traces of a former neighbouring building

Buildings from different age periods melt together in Manhattan

The Martinus Nijhoff Bridge in the fog

Almost midnight: the Siegessäule (partially) illuminated by moonlight
