The town was granted its Market Charter in 1214 by King John and continues to hold a market to this day. In the 14th century religious reformer Canon John Wyclif was Rector in Lutterworth's Parish Church of St. Mary between 1374 and 1384, and it was here that he is traditionally believed to have produced the first ever translation of the Bible from Latin into English.

The Great Bridge over the Charles River connected Cambridge, Massachusetts to Little Cambridge, which was the name for Allston-Brighton before it separated from Cambridge in 1807, first becoming the town of Brighton and finally joining the city of Boston in 1874. The Great Bridge was built in 1660-1662 at what was then called Brighton Street, and was the first bridge to span the Charles. A toll was authorized in 1670, rebuilt in 1862.

"Battle ground at Concord. This view, looking southeast, is from the road leading to the village, by the way of the North Bridge, to the residence of Mr. Prescott Barrett. The point from which the sketch was made is upon an elevation a little north of that where the militia assembled under Colonel Barrett. The stream of water is the Concord, or Sudbury River. The site of the North Bridge is at the monument seen in the center of the picture. The monument stands upon the spot where the British were stationed, and in the plain, directly across the river from the monument, is the place where Davis and Hosmer, of the American militia, were killed. The house, the roof and gable of which are seen in the distance, just on the left of the largest tree, was the residence of the Reverend Dr. Ripley (afterward a chaplain in the army) at the time of the skirmish. It is upon the road elading to Concord village, which lies nearly half a mile beyond."—Lossing, 1851

A lattice bridge is a form of truss bridge that uses a large number of small and closely spaced diagonal elements that form a lattice. It was patented by architect Ithiel Town in 1820 and 1835 as Town's lattice truss. Originally a design to allow a substantial bridge to be made from planks employing lower–skilled labor, rather than heavy timbers and more expensive carpenters, this type of bridge has also been constructed using a large number of relatively light iron or steel members.

The Maria Pia bridge (Ponte Maria Pia) is a railway bridge built in 1877 by Gustave Eiffel in Porto, Portugal. Built of wrought iron, its two-hinged crescent arch carries the railway line to Lisbon for 353m across the River Douro at a height of 60m. Eiffel's design was the least expensive of eight entries into an 1875 competition, being 31% less than the next lowest priced. The bridge was built to avoid a 12 km detour, and started on 5 January 1876 and completed on 4 November 1877. At that time its span of 160m was the longest arch bridge in the world, the previous record holder, at 156m, being the Eads Bridge over the Mississippi at St Louis. The bridge was opened by the king of Portugal and named after his queen Maria Pia.
