Merchiston Tower
Merchiston Tower (Merchiston Castle) is a 15th-century Scottish tower house built around 1454 for the Napier family and later the birthplace of John Napier. The L‑plan stone tower stands at the centre of what is now Edinburgh Napier University's Merchiston campus. It served as a fortified country house and has been restored and incorporated into the modern campus.

As it stood in 1454
The shape it held in its prime.
A compact L‑plan medieval tower house of roughly four storeys, built of irregular, mottled red‑brown sandstone blocks. The south face contains a tall, shallow recessed second‑floor doorway (for a drawbridge) and vertically aligned small windows; a corbelled parapet with projecting corbels runs around the top. A small round angle tourelle with a conical slate roof projects above the parapet, while tall rectangular chimneys and a stepped gable punctuate the roofline. The tower sits directly amid an enclosed yard and neighbouring buildings.
Its story
The story of Merchiston Tower.
Merchiston Tower was probably built around 1454 by Alexander Napier, 2nd Laird of Merchiston, on lands his father had acquired before 1438. An L-plan tower with its wing projecting north, it carries an unusually elaborate main entrance at second-floor level, set in a tall recess that once housed a drawbridge. It serves as the seat of Clan Napier.
Its most famous son is John Napier, 8th Laird and inventor of logarithms, born here in 1550. The Napiers held Merchiston for most of five centuries, though not unbroken: sold in 1659 to Ninian Lowis, whose family kept it until 1729, it was reacquired in 1752 by Francis, 6th Lord Napier, then sold again in 1772 and passed through several further hands.
Let to Merchiston Castle School, the tower gained a castellated Gothic-style extension, since removed. It now stands at the centre of Edinburgh Napier University's Merchiston campus, where a corridor runs through the castle itself to link the surrounding campus buildings.
