Ancient wonders are all well and good, but many modern feats of engineering can be just as jaw-dropping to experience and are often a lot easier to visit. We present a selection of some of modern mankind's most impressive works of construction, varying from the supremely useful to the purely entertaining.
Built: 1889
Where to find it: Paris, France
10,000 tonnes of steel make up one of Europe's most recognisable structures, a true engineering marvel that continues to wow visitors more than a century after it was constructed.
What to do there: Climb up, admire views of Paris, propose to a loved one, eat at one of the two restaurants within the structure.
