(No, the "temple" is not the small wooden thing with a pigeon on top you see on the photo.)Of what used to be called the Temple, hardly anything remains. Today you can visit a small park, Square du Temple, but here you will find nothing which reminds you of what the Temple used to be. However, some very minor traces do exist. But, let’s first try to get an idea of what the Temple really was. 
Originally the Temple was a medieval fortress, built for the Knights Templar (or the Order of the Temple) during the 13th century. As this Order was dissolved soon later (“tough” actions by the Avignon Pope Clement V, King Philip IV... ), the Knights Hospitaller (of Jerusalem, Rhodes, Malta...) took over and remained until the Revolution.
On the plans I show here, you can see what the Temple looked like in 1739 (from the Turgot plan), including church, chapel, hospital.... Some special attention is of course drawn to the Tour du Temple (the Temple Tower, the “Grosse Tour”, “Grosse Tower”, “Grande Tour”) which dates from 1306. It served immediately partly as prison, more and more with the time. It’s especially known for having been the prison of the Royal family after the Revolution. Louis XVI left directly from here to the guillotine (see previous posts); Marie-Antoinette was transferred to the Conciergerie (see previous post) for a short while, before it was her turn....

Compared to the 1739 plan, some modifications had already taken place when the Royal Family arrived in 1792. Obviously some of the walls were already demolished. The “Grosse Tour”, which had its place just behind the park corner you can see on the top picture (traces have been painted in the street just behind - in front of the local 3rd arrondissement Town Hall), was destroyed in 1808, and soon also most of the other buildings. The home of the “Grand Prior” which in the meantime had been used as home of members or “friends” of the Royal family (the young Mozart was invited to play here) remained until the middle of the 19th century and the Haussmann modifications.
What remains than today of the Temple?Hardly anything. The doors of the “Grosse Tour” can be found at the Château de Vincennes (photo from Wikipedia) and a wall corner tower remains in the yard, between some apartment buildings which you cannot access (unless living there or being invited of course). (See plan above.)
The doors of the gate to a house close by (1 rue Saint-Claude) are said to come from the “Grand Prior” building. (It happens also to be the place where an impostor, Joseph Balsamo, “Count of Cagliostro”, lived in the 1780’s. He was heavily involved in an affair called the “Collier de la Reine” (Queen’s Necklace).After the demolition, the park, Square du Temple, was created. Just north of it, a first covered market was built in 1811, replaced by a large cast iron version in 1863, but a few decades later in its turn partly replaced by apartment buildings. However, a small part of the “Marché du Temple” (specialised in clothes and textiles), the “Carreau du Temple”, remains - today under modification to become a local centre for cultural and sports activities.
