The twisting staircase linking the north-east corner of King's Park with the river below is a firm favourite with Perth exercisers and holds an insight into the past.

Heritage Perth's Richard Offen said the stairway, known as Jacob's Ladder, was built because it was cheaper than building a road to link the areas.

"As early as 1905 people living near the top of Mount Street and Cliff Street began to campaign for a connection to the riverbank at the foot of Mount Eliza," he said.

"Their original demand was for a road, but given the steep incline, it was decided it would be much cheaper to build some steps."

In 1909 a straight staircase of 274 jarrah steps was built for the price of £171.

It was initially known as the Cliff Street Stairway but acquired a new name early on thanks to a local real estate agent.

Jacob's Ladder referred to the staircase to heaven dreamed of by Jacob in Bible Old Testament, which allowed angels of God to travel between heaven and earth.

"According to local legend, in the early years of development around the periphery of King's Park, the houses perched on the top of Cliff Street were considered to be among the best in the city, because of the stunning views of the river," Mr Offen said.

"This seems to have inspired a local real estate agent, Cyril Dent, to place a sign near the base of the newly-constructed staircase announcing, 'This way to Jacob's Ladder'."

The ladder quickly became a popular place for play, with many boys using iron sheets to slide down the sandy tracks on either side of the new staircase.

Life on Perth website's history of the ladder states that "those lucky enough finished their rides unscathed in the Chinese market garden at the bottom".

"Others became entangled in the council installed barbed wire, and walked away more shredded than the cabbages that were intended to soften their landing," the website stated.

By 1961 the Perth City Council decided the rundown wooden stairs were no longer safe and closed the ladder.

"This move met with public opposition and consideration, albeit briefly, was given to building a light railway up the hill, but as soon as they saw the cost the council decided not to do it," Mr Offen said.

"They decided to build a new staircase which cost £7,500 and that is the concrete staircase we know today, which is in a spiral formation."

While the market gardens are long gone, Jacob's Ladder is a popular place for exercise, and busy with people running up and down the 242 steps.

To reduce noise for people who live nearby, council has disallowed organised exercise classes from using the ladder and surrounding area in the evenings and early morning.
