At the junction of Love Lane and Aldermanbury in the City of London, there is a small park. If you are in the area, it’s well worth a visit.
The parklet is on the site of St Mary Aldermanbury. A large marble plaque tells the history.

Site of the Church of St Mary Aldermanbury First mentioned in 1181. Destroyed by the Great Fire in 1666. Rebuilt by Wren. Destroyed by bombing in 1940. The remaining fabric removed to Westminster College, Fulton, Missouri, USA 1966 and restored as a memorial to Sir Winston Churchill. This plaque placed by Westminster College.
The plaque has a picture of the restored church:

I sat next to the plaque, under what must have once been the West window. Here is the view, looking South.

In the foreground of the picture you see ancient stones, which look like the bases of the pillars of the Nave. Evidently not quite all of the church was exported to Fulton, Missouri.
The two flowering trees are magnolia, currently in bud. Between them, on that raised garden, is a bust of Shakespeare, and a memorial to two actors who published Shakespeare’s First Folio.

To the Memory of John Heminge and Henry Condell Fellow Actors and Personal Friends of Shakespeare They lived many years in this parish and are buried here --- To their disinterested affection the world owes all that it calls Shakespeare They alone collected his dramatic writings regardless of pecuniary loss and without the hope of any profit gave them to the world They thus merited the gratitude of mankind
Equally interesting is the inscription below this plaque:

Charles Clement Walker (1822-1897) was a benefactor for various memorials in London, according to this post on the marvellous “London Remembers” site. He was a wealthy civil engineer, employing 400 people in Shropshire.
Near this monument is a tile let into the low wall:

The Aldermanbury Conduit Stood in this street Providing Free Water 147-18th Century.
The water for this conduit originally came from the Tyburn river near Bond Street, according to a post in LostCityofLondon.co.uk.
There is much of interest in this small space. Across the road is 10 Aldermanbury. This was built in 2000, by Legal and General as an HQ office for a broker called Flemings. It is now a multi-use office occupied by financial services and consultancy organisations. Do not miss the amazing artwork on the corner. At first I thought it was just a weird artwork. Then I realised it was the building number: 10.
The picture was drawn on location and coloured later. Here is work in progress and maps. I will return to this location, it’s a wonderful tranquil green spot. Recommended.
