Learn Portuguese (Portugal): O campo onde jogamos râguebi fica perto da escola. - The field where we play rugby is located near the school.

No. Even though you are learning about ao encontro de, that phrase implies motion (moving towards something to meet it) or metaphorical agreement. Because the field is in a fixed, static location, you must use a standard preposition of place like perto de (near) or junto a (next to).

Why use fica instead of está or é for "is located"?

While you could use é or está, European Portuguese strongly prefers the verb ficar (literally "to stay" or "to remain") when expressing the permanent geographical location of a building, field, or city.

Could I say em que instead of onde here?

Yes! While onde literally means "where", it is very common and grammatically correct to use em que (in which) when referring to a physical location. So, O campo em que jogamos... means the exact same thing.

How do we know jogamos is in the present tense here rather than the past tense?

In European Portuguese, the present tense "we" form for "-ar" verbs is spelled jogamos (with a closed "a" sound). The past tense requires an acute accent: jogámos (with an open "a" sound). This strict visual and auditory distinction makes the tense immediately clear in Portugal.
