& # 39; Ice artists & # 39; spend 10,000 man hours to create incredible 40ft-tall frozen castles

& # 39; Ice-artisans & # 39; have created incredible ice structures that are over 40ft high.

The frozen castles at William Hawrelak Park in Edmonton, Canada look like natural glaciers, but are made by hand from thousands of individual icicles.

The structures need up to 30 builders of about 10,000 man hours to create – and even have slides, thrones, fire pits, dancing LED lamps and fountains built into them.

They were iced with ice crystals and some of the gigantic constrictions were formed to 10,000 of the ice.

The icicles are grown on racks that are sprayed all night and left to freeze in a process that starts in October and lasts until the end of November.

Builders then place the icicle-like building blocks until the structure is about 40ft high.

Then they form and form the castles.

Ice Castles, the company that builds the structures and is then open to the public in January through March, after which they are flattened and discarded.

The beautiful images of the towering ice forts were captured by photographer Joe Chowaniec who said temperatures could drop to around -15 degrees Celsius.

The hand-placed icicles are then sprayed with water before the process is repeated over and over until the ice reaches a height of about 20ft to 40ft.

The 50-year-old, who lives nearby, said: "The day I took the photo it was about seven degrees Celsius, but the ideal temperatures for building are around -8C to -15C.

Each location has a crew of around 20 to 30 builders working in a combined 4,000 to 10,000 man hours over a period of four to six weeks that build the ice castles.

We call them crew ice makers because they really make a work of art out of ice.

& # 39; At the end of the season in March, they bulldoze it and let it melt.

& # 39; They rebuild it every year, so every castle is completely different.

& # 39; They start in October by preparing the groundwork and by the end of November they start building the icicles again.

It's really something to see – you can go several times, different times of the day in different weather conditions and experience something completely different each time.

& # 39; My favorite time to visit is about an hour before sunset and watch it light up when the sun rises. & # 39;

Crew members often call themselves icicle farmers or ice builders.

Icicles are grown on racks, sprayed with water at night and then harvested every morning.

Up to 10,000 icicles are harvested and placed by hand using a patented process to build the castles.

The hand-placed icicles are then sprayed with water before the process is repeated over and over until the ice reaches a height of about 20ft to 40ft.

During the season, the ice makers continue to build the castles and maintain the integrity of the ice structures.

Daily tasks include taking care of the floor of the castle, which consists of crushed ice and snow.

Crawl spaces have been carved out so that guests can move around the castles and this process also ensures that the slides and throne are maintained.

This often requires additional chiselling or carving throughout the year.

At night, fire dancing is held within the structures.

Hundreds of thousands of visitors come to the six different locations in North America, where Icy Castles make the structures, including Colorado and New Hampshire.
