Île de Peilz, or Peilz Island, is small picturesque island in Lake Geneva in Switzerland, not far from the town of Villeneuve. Measuring somewhere between 20 and 77 square metres, depending on different sources, it is often described as the smallest island in Lake Geneva and possibly the lake's only natural island. A solitary London plane tree dominates the entire islet, its broad canopy visible from passing boats and from the shoreline. This tiny speck of land has inspired poets, generated local legends, and become one of the most photographed features of Lake Geneva.

On Smedestraat, a shopping street in the historic center of Haarlem, in the Netherlands, is an unusual national monument. It’s not a house, church, or public building, but a 17th-century brick gateway with a wooden door. Its significance lies in both its architectural details and what it reveals about the historic urban fabric of Haarlem.

The gateway dates from the second half of the 17th century and is protected because it preserves a rare and attractive example of period brickwork. The most distinctive feature is the blind circular window (a decorative round opening that is not actually a window) incorporated into the masonry above the archway.

In a small village on the outskirts of London stands a barn so vast and magnificent that it has often been likened to a church. Its soaring timber arches rise high overhead, and its cavernous interior inspires the same sense of wonder that one expects to feel inside a medieval cathedral.

This is Harmondsworth Barn, and it was built more than six centuries ago to store grain harvested from the surrounding fields. Today it is widely regarded as one of the finest and best-preserved medieval barns in Europe, a masterpiece of timber construction that demonstrates the wealth, ambition, and engineering skill of medieval England. The poet and architectural campaigner John Betjeman was so impressed by the building that he famously described it as "the Cathedral of Middlesex."
