Mauritius Martello Tower 
Heritage Museum 

Who would expect to see a Martello Tower alongside our tropical beach?
The mighty fortress stands guard at La Preneuse on the South West coast of Mauritius. One of the best example in the world!  Her cannon overlooks our gentle turquoise lagoon. An unusual sight not to be missed.

Origin of the Martello Towers

The British came across one of these fortresses during a fierce battle at Mortella Bay in Corsica. The year was 1794. The tower was manned by the French who had mounted cannons on the roof top. The British were so impressed they decided there and then to build similar towers to protect their empire. 

You can still see remnants of these towers in some ex-colonies and alongside the shores of England. They have a conical shape with thick walls and some variations in between.

The Mauritius Martello Tower has been lovingly restored and transformed into a Heritage Museum. Here she is, tucked away among casuarina trees.

Martello or Mortella?

By the way ‘Mortella’ has nothing to do with ‘Martello’. In case you think it's a spelling mistake ... 

  • Mortella Bay is named after a type of shrub which is abundant in the area of Corsica where the battle took place.
  • Martello means hammer in Italian. In the olden days one would lit a fire on the flat roof of the tower to warn of approaching enemies. On the West coast of Italy the alarm was done by striking a bell with a hammer or ‘martello’. 

Why Martello Towers in Mauritius?

These towers are an important part of our history and culture. Let’s go back to the beginning of the 19th century after Mauritius was captured by the British. Slavery was being abolished. Free labour was coming to an end. What would happen to the economy based on sugar cane?
The British were worried about a French insurrection.

The British decided to build 5 of these fortresses alongside the West coast to protect the island. The coastal batteries were erected at strategic locations near river mouths.

How were they built?

Mostly with basalt rock. Royal engineers were commissioned together with skilled stone cutters from India and carpenters. As usual slaves were used for heavy labour. Their task was to erect sand dunes called batteries in front of the towers.
Two cannons were installed on the flat roof top.These could be rotated through 360 degrees.

The construction of the 5 towers took three years .

It turned out the towers never saw any action. They were abandoned and over the years some stone walls have crumbled. Gone were the teak beams and lead piping. Fortunately some cannons and cannon parts were recovered and displayed near the Tower.

The Martello Tower Museum

In 1992, ‘Friends of the Environment’ started restoring the tower in La Preneuse with funds from the Government and other institutions. It was beautifully restored into a museum which was opened in 2000.
An important part of Mauritius National Heritage Site. 

These fortresses don’t have doors on the ground floor. One had to climb a ladder to an opening on the first floor. Once there a ladder was used to reach the ground floor.  

Don’t panic you won’t have to climb any ladder to visit our national monument. A door and a staircase were constructed on the ground floor for convenient access. Look at the thickness of the wall in the image below.

Inside the Museum

The tower has several floors:

  • The basement where a tank was constructed for storing rainwater collected from the roof via pipes.
  • The ground floor used as a storeroom with an armoury for gun powder.
  • The first floor with a room for the exclusive use of the Chief Officer. Other rooms would accommodate soldiers.
  • The flat roof were the cannons were installed. One facing the sea and the other facing inland.

Have a look at the interesting memorabilia on display. Muskets, the officer’s deck and uniform, a fire place with various utensils and much more. 
Photos of the inside are only allowed for private use. You’ll have to see this gem for yourself when you are on holiday in Mauritius.

Martello Tower Location

Easy to find. She is located in Black River off our South West coastal road. 

1. From the North, drive past Tamarin and before you arrive at Black River or Riviere Noire you’ll see a ‘La Preneuse’ sign. Turn right and the Tower is about 1 ½ km down the road.

2. From the South, drive past Black River, turn left into La Preneuse road shortly after a football field. The Tower is about 1 km down the road.

I have included a stop at the Martello Tower in my West coast beach itinerary map.
