What kind of chestnut tree might this be?

[Mainer]

This tree is growing in Portland, Maine. It is huge, and apparently likes the weather here. Although, to be honest, I don't!

I'm no expert on Chestnut trees, but I'd love to have just a little of your weather here in Texas in July, August, and September...but wouldn't trade any other months.

A guess might be a horse chestnut tree which has the more rounded leaves.

To be frank it looks more like a Beech tree. Does it have any prickly or spikey cases in late summer for the nuts, if it is sweet chestnut?

Sorry that isn't Aesculus, a chestnut tree. Below is an image of how the leaves look...

Is it possible for you to take pictures of the leaves and stems away from the light. Also a full picture of the tree and close up of the bark please.

Could be a Castanea chestnut. Although not American Chestnut, the leaves are too round and not elongated. Then there’s the whole blight thing.

The street I live in is lined on both sides with these beautiful trees - no mistaking them. When the conkers are ripe they drop from the trees. You can hear loads of "boing" noises and thuds as an unwary car driver has parked under a tree!

I don't think the tree is Sweet or Spanish Chestnut either as they usually have a serrated edge to the leaves which are generally longer. At this time of year they are covered with bright green, soft, spiny cases which contain nuts. Maybe some variant form of Chestnut tree if at all!

How about this Broadview Walnut tree?

 

[Sheal]

I know nothing about walnut trees @blenor but making comparisons I think you may well be right.

Spoke to the owner of the property. It's a Northern Catalpa. Has pods that look
like string beans--which were only visible from the other side of the street, since they were so high up. Thanks to all for suggestions!

 

[Meadowlark]

Interesting. I grow the Southern Catalpa tree mainly for the food source for the catalpa sphinx moth whose catalpa worms are outstanding fish bait/food.

Didn't recognize your Northern Catalpa.

There are 2 tees growing together. The first picture is absolutely NOT a Catalpa. The leaves are the wrong shape and size. Nor is it a walnut or Horse-chestnut. Both of those have compound leaves and the first tree does not. Some closeups of the stems and leaves of the first tree would help clarify things.

I would tend to agree, catalpa has large leaves as I remember, I think it is a bit chilly for them here, but I have seen them in Spain. Those twigs are very delicate, so not ash, which does have leaflets in pairs, and the tree looks too big for walnut, but maybe that's just how they grow here. I look at the overall habit, the colour and type of bark and the buds and twigs as well as the leaf. I might have guessed hornbeam, except I think the leaflets are alternate rather than in pairs, I think the same is true of lime. The very best clues of course would be flowers and fruit.
Just by the by, we only have about 35 native trees in the UK, and only two conifers, Scots pine and yew, but people have been importing trees since the Romans brought in poplar trees for the bees, so we now have about 350 species that are naturalised here.

I looked closer at the second and third of the last pictures and I can see that the first tree is growing to the left of the Catalpa. Leaning away from it. Still can't identify it though.

 

[Meadowlark]

Sure does look like the Northern Catalpa tree to me...even down to the "fruit" which often looks like green beans. I'm going with the property owner's call...Northern Catalpa.

Here's the classic green bean look of the Northern Catalpa...

 

[cpp gardener]

The first picture is absolutely not a Catalpa. The leaves are a completely different shape and size. The second set of pictures includes both the first tree AND a Catalpa. The first tree is growing underneath and to the left of the Catalpa. That’s the one we need more pictures of to identify.
