Essex has some unique tourist attractions, but perhaps the most unusual is the \'secret nuclear bunker\', which is clearly marked on maps and road signs.

The Kelvedon Nuclear Bunker was originally built in 1952 as an emergency regional defence site. In the event of a nuclear attack, the bunker could house MoD workers and senior civil servants for three months. They would than be tasked with rebuilding the country.

Nowadays, the bunker, which was secret when it was operational, is kept as a museum, where visitors can learn about the history of the Cold War.

Less unusual tourist attractions, but no less spectacular, include Colchester Zoo. Hundreds of thousands of people visit the zoo every year, to see its celebrated collections of primates and big cats.

However, there are many other areas in the zoo, featuring birds, meerkats, mountain goats, terrapins and much more. Colchester Zoo engages in captive breeding programmes to combat the declining numbers of animals in the wild.

You may feel inspired to take in more nature after visiting the zoo. In this case, you can enjoy relaxing walks along any of the rivers in Essex, such as the River Brain or the River Crouch.

For a really relaxing day, or for a break during a walk, you could sit back and try fishing on one of the rivers.

Of course, you want a more exhilarating visit to Essex, in which case you should come during the V Festival.

Showcasing British and international acts, the festival takes place at the end of August each year. The often unconventional line up means there is sure to be something to please everyone.

If you are more of a history buff, you can visit sites such as Audley End, Hedingham Castle and Mangapps Railway Museum.

Hedingham Castle is a fine example of Norman architecture and is a remarkably good state of repair. Especially when you consider that it is around 1000 years old and has been fought over in vicious battles.

Colchester Castle is another must-see for history lovers. Completed in 1100, it now stands in a beautiful public park. Visitors can tour the castle and view many interesting artefacts from the castle\'s past.

There is a wide range of tourist attractions in Essex, from art galleries and museums which you would expect to find in any county, to the not-so-secret \'secret nuclear bunker\'.

Booking coach hire in Essex is a great way to learn more about the county and the various tourist attractions.
