Secret additions to tourist attractions around the world
<p>An apartment in the Eiffel Tower, a tiny police station in a lamp post, secret passageways and unmarked floors.</p>
<p>These may sound like ideas straight from a spy movie, however, they are just some of the real - but hidden - additions to popular tourist attractions around the world.</p>
<p>While some are disguised, others can be spotted – if you know where to look.</p>
<p>One of the most iconic structures in the world, the Eiffel Tower in Paris, contains an apartment, Express.co.uk reported.</p>
<p>In 1889, engineer Gustave Eiffel had a private apartment constructed near the top of the 320 metre-tall tower.</p>
<p>In London, Trafalgar Square has an ornamental lamp post that once doubled as the country's smallest police station.</p>
<p>Inside, it had room for two prisoners, a phone line to Scotland Yard and a vantage point to watch crowds in the busy capital city.</p>
<p>While it was constructed in 1926, it is now reported to be used by council cleaners to store their equipment.</p>
<p>London has other hidden structures, too.</p>
<p>Beneath a section of the city's A212 road is the abandoned Crystal Palace station subway.</p>
<p>Although the station, built in 1865, was destroyed by fire in 1936, the subway was later used as an air raid shelter.</p>
<p>Parts were later used for the odd party and by children to play in but it was blocked off in 1990, the Express reported.</p>
<p>Some parts of the station remain and attempts are being made to reopen it.</p>
<p>In New York, hidden, private or now-unused spaces in tourist attractions seem common.</p>
<p>The Statue of Liberty's torch was once accessible to the public, but it was closed after it was damaged by a German act of sabotage in 1916, according to AM New York.</p>
<p>Now, the highest point which can be visited is the crown.</p>
<p>Many believe the top floor of the Empire State Building is 102 - but there is in fact a floor 103.</p>
<p>A small balcony with low railings, it is often only used by celebrities, according to the Express.</p>
<p>At the Grand Central Terminal, unknown to most, is a tennis club.</p>
<p>Located in the upper floors of the building, the Vanderbilt Tennis Club has been operating since the 1960s.</p>
<p>The Waldorf Astoria hotel in the city has its own secret underground railway.</p>
<p>President Franklin Roosevelt used to travel from his home using the underground route, the Express reported.</p>
<p>Also in the US, Mount Rushmore is home to four huge granite statues of former presidents; George Washington, Thomas Jefferson, Theodore Roosevelt and Abraham Lincoln.</p>
<p>Behind Lincoln's head is a hidden room, the Hall of Records, where documents tell the nation's history - but tourists are not allowed.</p>
<p>At Rome, Italy's Fiumicino-Leonardo Da Vinci Airport stands an almost 20-metre statue of the painter and inventor the airport takes its name from.</p>
<p>Although it was built in 1960, it was not until 2006 that a worker found a hidden compartment half-way up the structure with two documents inside, according to Atlas Obscura.</p>
<p>Both were written in classical latin, one revealing details of those who were at its opening ceremony and the other, the history of the area.</p>
