It's not necessarily just teleports (that will become available to you when you get the Spire, the only feature that gives them routinely as prizes). Since you started your city before the recent [Ch1-5 random new city test of new mechanics] changes, I'm going to guess that will be when you open Ch3.
Both my cities are 'parked'; one is at the beginning of Ch18 (first tech of new chapter activated), the other is at the beginning of Ch16. The reason for activating the first tech in the city is for the game to see you as 'in' the higher chapter. That will make all event/crafted bldgs give rewards for the higher chapter level.
I parked them because I despise the long slog through these higher chapters. It's not a challenge, they just made it take a gazillion [whatevers] to do anything and then made the bldgs that produce those things make like 10 of them a day max. They also made sure they're the uncapped resources, so not even Portal Profits help. Yes, there's a lot of stuff in there that won't make sense to you until Ch6 when you first see the guest race chapters, but hopefully you get the general idea of why I personally am disillusioned with chapter progress. Some players love it; I hate it.
I looked ahead and found a pretty blue dragon AW available at the end of Ch17, so I slogged that city through 2 chapters just to get that AW. Didn't know what it did or gave, just wanted it
And I love it, just not enough to do it again in the other city, lol! My favorite parts of the game are tourneys, Spire, events, and FA's (in one city; can't handle doing FA's in two, lol!). I do use teleports to move bldgs in and out of my city as needed to produce resources I need for those activities. That 2nd city has been parked in Ch16 for well over a year and I'm still happy playing it. I make my own goals (ex: increase tourney average to xxxx sustainably week after week).
