Sometimes all we get to see of a building is its front door, especially in a city like Edinburgh where many of the historic properties are still actively used as houses or commercial premises.
I don't take tours inside any of the paid entry attractions (although I may take you into a few choice locations on our tour!) so I'm used to only seeing the outside of a building.
Here are a few of my favourite doorways of the city, with some stories about the history hidden inside...
17 Heriot Row
Heriot Row remains one of the New Town's grandest addresses, and property on the street routinely sells for in excess of £1.5 million... Notable residents of the street include the physicist James Clerk Maxwell, and John Buchan, an author best known for his adventure story The 39 Steps.
Number 17 Heriot Row was the childhood home of Robert Louis Stevenson, and it is reputedly from a drawing room window on the first floor that he would stand looking out at other children of the neighbourhood playing in the private gardens on the other side of the road. In those gardens is a pond with an island, and it may have been those early experiences which fed his later iconic adventure story, Treasure Island.
4 South Charlotte Street
Another New town address, on the corner of Charlotte Square at the west end of the city. Number 4 South Charlotte Street was the birthplace of Alexander Graham Bell, who would later go on to lodge a patent for his invention of the telephone.
It's a useful reminder that before the New Town was the commercial district we see today, this area was built as a residential area for high-status families.
2 Advocate's Close
Just off the Royal Mile near St Giles' Cathedral is one of the most picturesque of the city's closes and wynds. Advocate's Close was formerly home to one of Scotland's Lord Advocates - the highest legal figure in the country - called Sir James Stewart. Stewart's house was actually at the bottom of the lane, but this doorway near the top of the lane is a powerful reminder that some of Edinburgh's Old Town houses have been occupied for over 400 years - look at the date above the doorway to see when this property was first constructed.
As Lord Advocate, Stewart's most notable case was the prosecution of a young student called Thomas Aikenhead for blasphemy, in the 1690s. Aikenhead became the last person in the UK to be executed for blasphemy...
Further down the Royal Mile, off the Canongate, is Acheson House, built in 1633 for Archibald Acheson, a major figure in the royal court of Charles I.
The crest above the doorway features a cockerel on a trumpet, the crest of the Acheson family, and in the middle of the date is a diagram made of the letters AA and MH superimposed on each other - for Archibald Acheson and his wife Margaret Hamilton.
Into the nineteenth century the house wasn't such a grand property, having become a brothel known locally as the 'cock and trumpet'....
Today Acheson House houses Edinburgh World Heritage, the city's premier heritage and preservation body.
The churches of Scotland are often the oldest structures to have survived the passage of time, and at Duddingston is a church reputed to be the oldest on Scotland's east coast.
One former door into the church - long since closed off - has an archway and stonework which dates back to the church's Norman origins in the twelfth century.
The church remains an active centre of worship for the community.
Earl of Morton's House, Blackfriars Street
Blackfriars Street is another fascinating lane in the Old Town, widened in the 1870s from its original layout as a narrow passageway just a few feet wide.
On the west side of the street are some of the original buildings which survived the wholesale renovation of Edinburgh, including a building which was formally home of the Earl of Morton, one of the regents who ruled Scotland during the childhood of Mary, Queen of Scots.
Today the building is a youth hostel, but above its original doorway is a fascinating emblem of two unicorns, standing aside a crown. This was the royal emblem of Scotland before the union of crowns, when Scotland and England came under one monarchy, in 1603.
The later royal emblem - still commonly used today - is of a lion and a unicorn with a crown between them, but this earlier symbol is still visible on a few surviving buildings from the sixteenth-century.
Take a private Edinburgh walking tour to see more doorways with stories from Scottish history!
