The Summoner's Rift is the most commonly used Field of Justice.
The map was given a graphical and technical update on May 23rd, 2012 and remade from scratch on November 12th, 2014.
Summoner's Rift is located in a remote forest between Freljord, and the Ironspike Mountains. The Summoner’s Rift is one of a few locations in Valoran where magical energy is at its greatest concentration, making it a highly sought-after locale to pursue magical endeavors.
Historically, the forest where the Rift resides was the site of several battles between two summoner factions symbolized with the Stag and Owl crests, they sought out to use the natural magical energy of the area for their personal use.
The large amount of concentrated magic has mutated the local wildlife. From, to it has also attracted the attention of a powerful who currently resides in one of the battle torn ruins. , and are creatures made from local flora and earth infused to construct a magical being. The Rifts unstable magic has inadvertently cause the reemergence of , a large Serpent/Worm largely believed to be dead for centuries. It has his corruption affecting the land around him.
Other known creature that live in this area are species of forest chameleons, ducks, Antlermice, crows, dragonflies and butterflies.
The objective of Summoner's Rift is simple – destroy the enemy nexus. In order to do this, champions must traverse down one of three different paths (or lanes) in order to attack their enemy at their weakest points they can exploit. Both teams have their lanes defended by numerous turrets; each turret grows in strength the closer it gets to its respective nexus and each turret must be eliminated in order to gain access to the next turret in that lane. Cooperating with fellow summoners is an absolute requirement for success, as it is easy for a champion to find themselves ambushed by enemies in the lanes of the Rift.
The newest and most venerated battleground is known as Summoner's Rift. Traverse down on of three different paths in order to attack your enemy at their weakest point. Work with your allies to siege the enemy base and destroy their Nexus!
- 19000 unit distance from Blue Team Nexus Obelisk to Red Team Nexus Obelisk (measured with ).
- Three lanes to fight your way to the enemy base.
- A forest populated by neutral monsters of varying degrees of toughness, the toughest of which provide buffs and/or gold for your whole team.
- Powerful turrets defend key areas on the map. You must confront these in addition to your enemies if you are to make headway toward victory.
- A map dividing river that lies in neutral territory, allowing for quick travel between lanes.
- Two bases at opposite corners of the map, populated by a shop, a Nexus, two turrets to defend the nexus, two base gates that only the team aligned with the base can pass through, and inhibitors that suppress the other team's minions.
Summoner's Rift during its history had a total of four shopkeepers.
- The first one was a Manbacon. This is an infamous race that is living in Runeterra. Manbacionians usually set up shops in a small pack and they also like to smoke. He sold some standard starting items like the , the , the . He was selling his weaponry at both the Blue team and the Purple team bases.
- The second shopkeeper was an elderly male Yordle with a cart pulled by an animal resembling a big cat or a rabbit of an unknown species (PBE data mining posted here revealed it to be a "yonkey"). He replaced Manbacon and he was also present for both the Blue and the Purple bases.
- A pair of new shopkeepers replacing the previous vendor: in the Blue base there's an elderly female Yordle with a large animal resembling a Bantha from and in the Red base there's an elderly male otter merchant attending his shop inside a large hot-air balloon that got punctured.

Summoner's Rift Evolves
On November 12, 2014 a new update to Summoner's Rift went live for use on the Team Builder queue and all bot modes. Then in November 19 the updated Summoner’s Rift was released for all queues, replacing the old one entirely. This time the update has been more heavier than the previous one, and the map was remade from scratch, changing the overall art style. From the minions, to the monsters, the structures, the decorations, the vegetation and even the music it was all completely remade. The new Summoner's Rift is in all respects a new map, made preserving the spirit and gameplay of the older Summoner’s Rift. The new elements are:
- A new handcrafted artistic style to Summoner's Rift.
- Gameplay on the map is more readable than in the previous map. Making action the top priority on the screen rather than the environment.

Check out some Summoner's Rift concept art!
By Riot ForScience 
Summoner's Rift has come a long way since League's launch in 2009, but our latest update to ol' trusty was the biggest change in the map's history.
While all updates go through iterations and testing, Summoner's Rift required a huge team of artists to concept and sketch out art for months before we started working in 3D. To celebrate the end of SR's beta run, we're releasing a few of the concept art pieces the environment team created, complete with notes and insights from the artists themselves.
- SRU Concept Art Gallery
- The general layout of two long lanes extending on the border of the map and a middle lane between them, each crossed by a river, was inspired by the fan-made mod Defense of the Ancients, popular map for Warcraft III of which once Steve 'Guinsoo' Feak was serving as the main designer.
- The monster camps in this map were made to spawn everytime the same places since V18.104.22.168: before that, wolf camps and golem camps randomly alternated.
- Ghost can be found in the halloween version near the top of the river (Top Lane) just to the right of the top most brush found in blue's jungle. He will even attack passing and either do 1 damage or pop his if the bubble is up on the Autumn version of the map.

- A smiley face is a tribute to a smiley face that was present on the old map, which was also located on exactly the same spot, at the southern part of the map.
- "The Sword in the Stone" at the north-east part of the map is a reference to and to legend.
- A random cogwheels can be seen on the eastern part of the map.
- At the eastern entrance of the Red base, when first entering the map, a frog can be seen scurrying and falling to his death.

Summoner's Rift map has been used for certain special, limited-time, featured game modes that circulate in and out.
- During the Fall of 2013, Riot's first featured game mode was called One for All mode 
- The mechanics were similar to Classic mode, with the only different being that all champions on each team are the same
- This mode would later inspire the creation of the One for All: Mirrored mode
- An Icon was to be given by playing this mode.
- Between April 1 and April 13, 2014, Riot made Ultra Rapid Fire mode and since then this mode has been coming back each year for April Fools' Day 
- An Icon was to be given by playing this mode.
- The mechanics were similar to Classic mode, with the added twist of the mode:
- Between July 17 and July 27, 2014, Riot made Doom Bots mode.
- In this mode players fought against champions controlled by computer generated AI.
- The Bots themselves got enhancements to their abilities and passives.
- There were 3 levels of mode difficulty, with each level the bots would get considerably "cheaper".
- An Icon was to be given by playing this mode.
- Between April 1 and April 13, 2015, Ultra Rapid Fire mode returned for another yearly celebration of April Fools' Day 
- An Icon was to be given by playing this mode.
- The Summoner Rift concepts are usually done before Riot make 3D in-game models. Sometimes they will make a concept, but it does not work in the game. Examples: The design is hard to click on; Or it does not fit the environment; Or it does not look like tanky enough; or look weak enough; The creatures have to look, in relation to each other; at the correct power level or defensive power level. An environment piece has to be visually appealing but not distracting to champions or effects. All the concept work is about trying to answer those questions. Does it work with gameplay? Does it fit the big picture? Art serves gameplay.
- A Raptor, Forest chameleon, and Antlermice can be seen in classic splash art.
- The stag symbol of the Protectorate looks similar to shield.
- The owl symbol of the Magelords looks similar to the Porowl, a species of owls that live in Summoner's Rift.
- Summoners Rift Shopkeepers will be getting their Voice-over in future game patches, similar to the Howling Abyss shopkeepers.
- This map has ties with the Protectorate and Magelords showcased in lore.
