A brutalist concrete building with angular, protruding glass windows reaches towards a clear blue sky. A covered concrete walkway extends from the side of the structure, and tree branches with white blossoms frame the view from the foreground.
A large brutalist concrete building features a row of tall, metallic service doors beneath horizontal dark vents. An angular, multi-storey glass structure sits behind it, while a slender, textured concrete tower rises into the clear blue sky in the background.
A concrete industrial building features three identical vertical metal doors labelled T1, T2, and T3, each marked with high-voltage warning signs. Above the doors is a row of horizontal glass louvres set into a deep, overhanging concrete frame beneath a clear blue sky.
A tall, twin-towered concrete building rises above a wide set of stone steps. The structures have textured grey walls and a vertical strip of glass windows, set against a clear blue sky. Low concrete walls frame the staircase on either side, with leafy green trees on the left.
A tall, tapering concrete pylon with a grid of blue-tinted windows rises towards a clear blue sky. The base is constructed of textured stone blocks, and a large, weathered stadium structure with visible text is visible in the background.
A modern concrete tower features a prominent vertical glass façade made of rectangular blue panels. The tall, angular structure rises against a clear blue sky, with a smaller matching section visible behind it. Both sections are topped with small red safety lights.
Two massive concrete pillars stand tall against a deep blue sky, angled towards each other to create a narrow gap. The sun shines brightly through this opening, creating a dramatic starburst effect and casting the sides of the pillars into dark silhouettes.
A single white paper cup sits on a blue-tinted glass balcony balustrade. The balcony, framed by concrete pillars and an overhanging ceiling, overlooks a distant cityscape under a clear blue sky.
A tall, thin concrete tower with a vertical strip of dark windows stands on a paved plaza under a clear blue sky. Two smaller, multi-storey buildings with rounded, panelled designs sit in the background beside a road.

Strahov tunnel runs for 2004 metres, 60 metres underneath the Prague neighbourhood of Strahov. It officially opened to traffic on 2 December 1997. So close, if they hurried up a bit we could’ve shared a birthday.

The tunnel also contains a nuclear bunker with capacity for 15,000 people – see video here.
